 A portion of this video is sponsored by Salesforce. Watch till the end to learn more. Uh, yeah, I would. And we did. Not the whole PC mind you, just the case, but believe it or not, there are plenty of options out there for cases that you can download and print for yourself. Tons for tiny PCs and Raspberry Pis and even some full-size options like these ones. After a bit of browsing we stumbled across this beauty by Empiricus, the OPF1. We were like, dang! But it gets even better. We checked out their profile and found the OPF2 and this, this is the one. But, we had a small problem. While the Prusa i3 i3 mark 3S's that we have in our print farm here are great workhorses, they don't exactly have the biggest build volume. So we had no way to print the OPF2 unless we sliced it up into tons of little bits, which could be done, but would involve a lot of gluing, which wouldn't be the best for structural integrity. Not to mention that it would take a really long time. So we made a call to the fine folks at E3D. And if you don't know who E3D is, they're one of the top manufacturers in the 3D printing world, primarily known for their hot ends. So that's the part that melts the plastic filament and their extruders, the part that pushes and pulls the aforementioned filament. A few years ago though, E3D built something totally different that would push the boundaries of 3D printing as we know it, the tool changer. This bad boy is not for the faint of heart. Colin needed three full weekends to assemble it. But the finished product is unlike anything we've ever used before. E3D very specifically and intentionally does not market it as a 3D printer. They refer to it instead as a motion system. Let me explain what that means. Because it's not an off-the-shelf click and print machine, you can configure everything about it to your exact specification. So we started out with a fairly standard config, four Chimera 3D printing heads all set up identically with 0.4 millimeter nozzles, but with each loaded with a different color of filament in case we wanted to give our case a little flair. By the way, our filament spools are down here in this rep cord filament storage chamber that, see we've got our little desiccant pouches in here, actually has a built-in humidity sensor. Pretty sweet. To give you an idea of the flexibility that this affords though, maybe more colors, maybe that's not your thing. No problem. Throw some dissolving support material on one of them. Or maybe you prefer a variety of nozzle sizes so you could do the bulk of your print really fast just laying down big old thick lines of filament without sacrificing quality in the fine details bringing in a finer head for those. But none of what I said makes it a motion system. This does. Want a laser etch? Chuck a laser diode onto one of these nifty tool plates and away you go. What about a milling cutter to get perfectly machined surfaces or even a pick and place head if you want to build your own PCBs? No problem. I mean hell, you could probably reflow them right on the print bed. This thing runs on mains voltage and heats up like you wouldn't believe, peeking at about 200 degrees Celsius. And the Duet 2 Wi-Fi and expansion board that runs this whole thing, it's legit a small computer plugged into the back of the unit. It can support up to seven extruders and a crazy amount of inputs and outputs all while hosting its own web server so you can control it remotely, which is super handy for 20-hour prints, which is what this took. I feel really bad that I didn't get to use the full potential of this machine, but with some of these prints being over 20 hours and the timeline being really tight, like when a print fails 12 hours into a print, all of a sudden I'm set back a full day. So for most of these prints, I just used one extruder just to simplify things. Yeah, I mean, this is really cool, but the results are a little rough. That was actually accidental. So one of the hard parts of this printer is you need to slice it. You need to take your files and tell it where you want the colors to be. Yeah. And there is not a lot of support for tool changers. In fact, I use PrusaSlicer 2.4 Alpha 1, which came out like days before I needed to start printing things here. And it has pretty good support now, but it was a mess trying to get this thing working. The good news is a bit of playing Lego, not with this, and a few 632 screws later, and we end up with this. Surprisingly rigid too, which is kind of crazy considering that it's all just made of like hollow plastic. I think it's 20% fill then. I hope not, but worst case scenario, we just make more. That's true. Man, and this is such a unique shape compared to what you could do with metal. Like this would cost a fortune to CNC. Look at some of these curves and stuff. Well, yeah, the harder part is holding things when you're machining. So like how do you fixture that so that it doesn't just go sproing when you're machining and then the tool grabs it and chucks it across the shop? No idea. I mean, stuff like this. Big pockets. Really tough. Insets. Can't do them. Some of these arches are like really clean. Yeah. So some of these parts we did on Prusas, if it would fit on the build plate, because I needed to get more parts done in a set amount of time. But other parts, they're too big, so they had to go on the tooltune. Okay, what did this part? This part is clean. I think this is actually, it barely fits on a Prusa. It's a thin like three millimeters. So that's right off a Prusa, like no tuning. And that's why they're so great. Fun fact, our Prusas actually use E3D hotends. So the work was also done on an E3D component at least. So let's see if I can find one that's done on the big boy then. What you're holding there in the center was done. I didn't put enough top layers on that. And so you can actually see the pattern. Oh, yeah. The infill. Yeah, I can see it. Step one is for us to heat set all of the inserts. You can actually see we've got these super handy. These are actually the same thing that I used back when I did that build in the underside of a table. So these little insets, they have a threaded part in the middle. So that's where you screw into for the motherboard or for a standoff. And then they have this kind of like knurled or textured outside. So what you do with wood anyway, is you put them into a pre-drilled hole and then you hammer them in. But obviously that would not be a good idea with a case like this. So we are going to use heat. I've never actually done this before. Yeah, really easy. So we've got a Hakko 888D, my favorite soldering iron. And it's at, I think it's $669. Nice. Nice. And you just pop it in there and wait for it to heat up and it will sink in. Look at that. Oh, wow. That's clean, boys. That's insane. Now I just have to make sure I get them all at the same depth. That's super cool. Do we have a, do we have extra standoffs? You mess one up? No, no, no. No, I mean, do we have more than what we need? Oh yeah, we have every size we need. So we made it compatible with any motherboard then? Pretty much. It's ATX now, but it'll fit everything smaller than ATX. A lot of this build was just finding fasteners. There's no instruction manual with this. So everything had to be kind of figured out. I don't actually see enough clearance here to put standoffs. Are we supposed to screw it directly into the back? Standoffs. Oh, we're using plastic spacers. Oh, okay. All right. Now like a sudden, yeah, that works. My concern though is just that, oh yeah. Okay. Getting them in is going to be a real challenge. Yes, I see that. Yeah. The spacers do appear to be the right height though. So that's good. That was a concern. Here's what we're going to do, Colin. Okay. I've got an idea. Oh no. We're going to go backwards, upside down. Oh, oh, oh. Okay. I get you. So we're going to put them all on here. Wait, these are not all the same height. Yes they are. This one's not. All right. Thankfully we have some extras. Actually we had one extra. Oh crap. I need my screwdriver. We got to. No, no. Yep. But I have LTT store.com. Okay. Here's the idea. It's going to take teamwork. I've got all the spacers in place. And I am going to hold this like this. And then I'm going to drop this on top of that. You're going to put the case on top and then I'm going to screw it in from the underside. Okay. Oh God. We're not even close. Oh, there comes one. My mouth got talent, yo. That's definitely going. Okay. So the board's on there. Well, kind of. Let's do one more up here. Okay. There. That's using your head. Okay. We got three. Now the rest we can put down here. Okay. Oh, this is going to look sick. All right. Let's get the CPU in. Because it's an open air case, cooling is not a concern. So we went for some of the hottest, most performant components on the market, including a core i9 10900K. We could have gone 11900K, but we misplaced it. By we, he means me. Quantum magnitude CPU block. Thanks, CK. Oh, oh, so nice. Don't worry. The aluminum doesn't actually touch the water. So it's all good. Oh, there you are. There you are. Hi, D.U. Got a Seasonic Prime 1000 watts. Very nice. That's really smart. As well designed and relatively strong as it is taking the heaviest parts and putting them at the bottom. Really down low. Definitely. It's good for stability, right? You don't want to sit in way up here. Yeah. This is EKS FLT 240. Now this case is designed to run the FLT 240 that has an integrated pump in the back, but it didn't show up on time. So we're just going to use the standard res and then we're going to run a standalone pump behind it and just VHB it on the back. Oh, that looks awesome. Yeah. Oh, that's sick. I'm not as into EKS reimagined CPU block mounting solution, but it does look really good once it's installed. For RAM, we've gone with a set of 3200MHz CL146 from G.Skill here. Can't go wrong with those. Man, this is going to be a wicked fast machine. I mean, if you're going to download a computer, you better download a fast one, right? It's free real estate. For our boot drive, we went with a relatively pedestrian 500 gig crucial P5. And then for our mass storage, we went with these 5300 Pro SATA SSDs that are 7.68 terabytes each. Oh, this is a cool mount. Yeah. Not the prettiest thing ever because it looks like you're intended to have the interface facing the back, but you can put up to three SSDs in here. That's super cool. This is chunky. We went with an ASUS RTX 3090, 24 gigs of GDDR6X memory. A board that's like almost as big as the freaking motherboard. It absolutely dwarfs the rest of the machine, which was already pretty freaking overkill. Oh, my goodness. Like sticks way out of the freaking case. On the other side, it might be too big. No, no, it's exactly the right size. I love it. I just wish we had the active backplate for it. I know. So we'll have to keep an eye on VRAM temperature on the back. But realistically, with water cooling on the front, open air case like this, it's not going to be. It'll be fine. Oh, interesting. So the fittings come off the front. Yes. So here's the appliance. The fittings come off the front. It'll tuck under, goes through this very convenient hole. And then we're going to have the pump sit back here. Oh, VHV. And then there's a little slot if you look front wise. Yep, I see it. And then that's where water will come out. Oh, up, up, rad, rad. And then back down to dump here. Oh, in the top here. Yeah. So we'll have interesting. We'll have we're going to have two rads and then we'll have a little joiner up here. Got it. To make this front mounted fitting look not so atrocious is to just make a fitting snake. Going to be a lot of O-rings here. Not more than death's PC. We went full mad lad on this one. OK. Wait for it. Yep. Nice. It's in. For the water cooling, I used two right angles and an extender along with a regular compression fitting to get a nice, clean look to the front of the case here. And it comes out right over here. We're going GPU priority on this build. It's getting the coolest water. And then we're going up to the CPU. We talked about this in our roasting your setups video, but clean soft tubing definitely looks better than crappy hard line. And are we going dual rad here? Going dual rad. Oh, that's awesome. You might say it's rad. I know what you're thinking. How the heck does this go? Oh, the fans go first. Yes. Mount the middle fan before you put it on. And then it sits on top of these two fans. I think I forgot to get one and three quarter inch screws. So the fix there is I go to fast and all and I get screws. I think we can fix it another way. We just need open open corner fans. OK, so we just go find open corner fans. Let's go find some open corner fans. OK. This is why it makes me so angry when I see radiator optimized fans that are closed corner, because when you're open corner, you see this, you have so much more flexibility for accessing screws. Right. Whereas when you have a closed corner design, Noctua's is semi open. You can't really get in there because the head of the screw won't fit into this gap. So here's how it works. We've got open corner six thirty two screws going into the case here. Then we've got screws going all the way through the fans into the radiator for the other eight. So it's going to be perfectly firmly attached. Actually, probably better than most of my radiators end up being. One of the nice things about this material is it has a very low shrinkage rate. PLA shrinks. I was going to ask about that. It shrinks a couple percent. These are such big parts. The shrinkage rate is like point eight or something. It's sick. The cost to make molds to injection mold these parts in plastic or machining is like it would be crazy. Yeah, just not for this was two spools of thirty dollar plastic like not bad. Less than less than 60 bucks a material. This makes me feel like an early thousands McDonald's commercial. Ba ba ba ba ba baby. I am loving it. Hold on a second, Colin. I might have made a mistake. How grave of a mistake? Not too grave. Oh, you just didn't plummet into the pump. Yeah, I went right past the pump. Yeah. Yeah. That's fine. Just put chuck and elbow in there. OK, good luck, everybody. Here we go. Cutting it. Yeah, it really is too bad. We don't have that one with the built in pump. I mean, would have been perfect. It's common. What we're going to do is we are going to kind of we're going to kind of hang the pump there. So I'm just going to jam this barb fitting. This is a classic EK fitting here. Three eighths inch barb, really big barb head on it. It's going to kind of friction fit there. Go. OK, OK, it's on and it just sits right there. That's pretty good. It kind of works, right? Totally works. OK, here we go. You ready? Oh, you got to warn me before you start to. Ready? You ready? We're good, right? We good. Oh, God. That was not a good noise. OK, but this tube is on now. You know, if it breaks, we'll just print another. Yeah, this looks sick. This looks absolutely awesome. Should we put color in or just water in it? Water. All the cool kids run pure water. They know what's up. This is the front. This is the front? Really? The front's wherever you want. Yeah, the front is whatever you want to show. Yeah, there's no front I.O. So you kind of need access to it at the very least. You could just face it like it's so it looks so good. Like it's presenting. Yeah. Yeah. Little awkward. This is the workplace I created. I get it. Man, this thing must have been so much work to design. We talk about how difficult it would have been to manufacture this in a conventional manner, but even just designing something with this many curves and contours is not easy. Actual, true design. We're like taking something from a concept to a fully fleshed, beautiful industrial design thing. That's hard. Can I get an LTT store dot com cable tie? We've sold through them. You know what? We haven't yet sold through. Look at your own Linus plushie. We've got bearded and unbearded. I'm having a thought right now. Is it a dangerous thing? From an aesthetic standpoint, I would prefer to go from here to here. But from an ease of use standpoint, I would prefer to go from here to here. I think it looks better that way. You think so? Absolutely. Then that's what we're doing. Yeah. Okay, I think we just need like power cables. While Linus is out filming PC or an OPC, get subscribed so you don't miss that. The wiring has been tidied up, the loop has been filled, and I've run a few benchmarks to get some ideas on performance. We even tossed a mild afterburner overclock on, raising GPU core clocks 300MHz and 900MHz on the memory. And a quick run around Cyberpunk 2077 with video settings cranked all the way to insane, netted a rock solid 60FPS with DLSS off. Turning that on to balanced gave a 25% boost in frame rates up to around 80FPS. Similarly cranked settings in Battlefield V made for a very playable 110FPS at 4K with our temps under load settling in around 60 degrees. Totally fine. To make sure it wouldn't melt, I left a particularly spicy benchmark loading overnight. And thankfully it didn't melt. It's still here. Woo! A little bit of RGB and fan management and IQ and we end up with what we have here now. The cable mod cables really did a number to keep everything super tidy in the back. There's no real place to hide the cables and it's kind of okay. It's an open frame case. I think it looks great.
