 We were called out recently by Shank Mods in his super popular Hot Wheels PC modding video where he invited us to work on a dumb idea. Put a 3090 in a Hot Wheels chassis he offered as a present. Well, Christmas come early. Shank Mods is here and so is the hardware. There's just one problem. This isn't a half-length card. Smart Deploy.

Let's start by going over what we want to do versus the constraints of this tiny 9.6 liter case that's going to try to stop us from doing that. First of all, this big graphics card, where's it going to go? So it's going to be similar to how I had it on my other Hot Wheels PC. So we're going to cut out a slit right here. This case is really beat up. So it's a good candidate for doing lots of work on it. Okay, so you have a spot for the 3090, but I'm guessing that the power supply that comes with this thing isn't going to be enough. So the power supplies are from these Hot Wheels PCs are kind of infamous for just like getting toasted. We're going to be using a different setup for the power supply. We've got two of these SFX power supplies. They're 650 watts each. So we're going to take these two power supplies and we want to turn this whole area here and use it for something else. So we're going to take these power supplies and put them right up here along the top. That's going to fit. Like that. So they'll fit up top. Above? Yeah, so we'll have these two at the very top of the case. Together we're looking at like 1300 watts. Hopefully that should be enough. So that brings me to what other parts are we going to use? We're going to be using a 5800X 3D. The new one is Gigabyte Mini ITX motherboard along with two sticks of Ballistix RAM. I couldn't help notice this giant air cooler in here. So this is just what we have right now for kind of testing to make sure the whole thing works. But we're going to be running a liquid cooling loop for everything. It is going to be water cooled. Yes, so the whole thing the GPU and the CPU are going to be on a single loop. The case is actually pretty easy to take apart. You just remove two screws here at the top and then one in the bottom with this pretty sweet screwdriver. LTT store dot soon. So once you remove these two screws the whole chassis just slides right out. Oh, she's dusty. Ah, yes. This yeah, this one's fresh. It doesn't work. In your last video when you revamped a Hot Wheels PC, you basically just made like a super power version of most of the original kind of PC, right? Yes. So for mine, I tried to keep the optical drive, the floppy drive, and then I stuffed it with two hard drives. But for this one, because we're cramming so much more power inside of it, we're losing all of that. The airflow in the original case, we had two air intakes there and then we had this grill here. And that's all the air intake. By removing the floppy drive and the optical drive, we're going to get a lot more airflow in the front, which will help us cool the much beefier GPU. Is that going to be enough or should we think about maybe widening these or maybe putting a hole on the top or what do you think? That's something I considered, but I really want to try to keep the case as close to original as possible, kind of keep the same aesthetic. The airflow you gain versus what you lose. Like the spirit of the build. I don't think it'd be worth it. Being the Hot Wheels connoisseur that Shank is, he brought multiple. So let's just use this one so it's easier to see your plan for the cooling. Now we emailed back and forth a bit and you had an original plan. Yeah, so the original plan was this right here. We have an 80 millimeter grill and this is the only exhaust on the entire PC. So my original plan was to run another 92 millimeter custom loop here with a blow image on. There are 12 volt fans that draw about four to five amps. That should do a good job cooling it, but the issue is it's really loud. There's another problem with it though, was that Linus was actually really skeptical that that would even be sufficient cooling. So another plan we had was to put more tiny bloomin' matrons up here with another radiator, with another radiator here and just have radiators everywhere with bloomin' matrons, but that would just be so loud. Aside from putting radiators all over it, me and Alex got to work brainstorming through a video call. Alex came up with the idea of trying to fit a bigger radiator by moving the power supply. How big we talking, 120? So 120 millimeters. So what I was able to do was I had those Flex ATX power supplies and if we mount them to the top, this clears up where the power supply was rather than using an 80 millimeter exhaust for the 92 millimeter rad. We can cut this part out and have a 120 millimeter rad right here. There's another thing. At the top, we were talking about how this is longer than a typical 3090. How are we going to make this fit? Fortunately, the Hot Wheels PC itself has a bit of dead space. We're going to have to cut into the back of the frame and have a place for it to extrude a bit. And that will also provide support for the back of the graphics card. Okay, so we've got everything on an open air bench. And right away, I'm thinking this 120 millimeter radiator is looking pretty thick compared to the tiny chassis it needs to fit into. But what we're trying to figure out right now is, is this even sufficient cooling? So we have Furmark running to tax the GPU. We've got Prime 95 running to tax the CPU. And we've got hardware info open to monitor our temps. So we're going to see what they end up plateauing at. Now you might say that this isn't even a relevant test to do because it's an open air bench and it's going to be going into this completely, almost completely closed off chassis. But what we want to know is, do we at least have some headroom here? Like if it doesn't thermal throttle on this, that means we have some room to play with. And maybe there's a chance in hell that it'll work in here. But if it does thermal throttle on here, then we have to reinvent the wheel and think of another solution. Because if it doesn't work here, it's not going to work here. Okay, so we have our cooling loop set up and the game we're going to play here is, does Linus think this is sufficient cooling? Oh my gosh, I can already tell you probably not. Alright, so I'm going to aim the camera at it. You've got your water block 3090. You've got a 5800X3D in there. And there's your res. And this is your Chungus thick 120 millimeter rad. That's a cross flow rad, so I can already tell you you're giving up some there. So what do you think the temps are? We've been running Furmark for about 20 minutes as well as Prime95. Well, I can tell you I think that GPU is up in the like 80 degree range. And then I think the CPU is probably as high as like 70 plus. We've got the Furmark here. Shut up. 51 degrees after 26 minutes. Really? Okay, this might just work then. Yeah, you might just pull this off. Daddy's proud. We're going to modify this chassis to fit our 3090 in five steps. Step one is going to be to clean out and empty out this whole thing. So it's more like this. That means we're going to have to drill out these rivets and pull out these cages. Next, we're going to have to drill a hole here for the GPU. That's step two. And step three, the opposite side. Because remember the GPU has to stick out because it's too long. Step four is going to be cutting a hole for our power supplies. And then step five, cut a hole for our big old radiator. But I actually have a lot of other stuff to do in my regular job. So I'm going to get Tyne and do this for me. Oh, what? I originally used this motherboard on my previous build, but there's a few issues we're going to have to solve to make this one work. This bracket right here interferes with this little extrusion. So we're going to need to remove this plate. The other issue we have is right here, because this is a permanently affixed I.O. shield. This butt's right against this lip right here. So in order to make this fit, we're going to need to cut into the bed, because this is where it's all mounted. So after taking out this initial cut and realizing that this is kind of impractical, I just spent a little bit of time catting up what's going to be our back plate here with all of the cutouts for the power supplies, the GPU, as well as the I.O. shield and the radiator. And I'm about to cut out one of our test pieces before trying to go on to either our mill or our router to cut it out of metal. I cut out a thicker piece of acrylic that's also clear, so we have an idea of what's going on and also it's a lot more structural. And then the next thing we want to try to do is fit in the rad, which we already know is going to be not fun. So the radiator is the biggest thing. So right here, it's not, there's not enough space right here, and because of the cap right there is bumping against it. So the screws posts are barely not able to. So we had thought that maybe we can get away with taking this cap off, taking it off onto the Tormach and machining it flatter. So we have a lower profile bit because it has knurling on it so we can hand tighten it. And that might just give us enough clearance to let it fit in. Ready for more dumb idea? Oh, good. Instead of this, what if this? Uh, yeah. We had it kind of crooked. Yep. So then it was right up against there. That would give us more clearance for the GPU and a little bit more clearance there. So the only downside is it would look a little crooked on the back of it, which. That's fine. Which is fine. Yeah, we can totally do that. I'll cut out another one. Now that we've cut this hole out of the front of the case for the back of the GPU, it should be able to fit. You can slide right into there and click into place. Even though it is extruding out of this part of the case slightly, it's still within the range of that gap inside of there. So it'll fit right into the dead space outside, inside this case, but outside of this frame. So it fits right in. Some breaking news. Shenk Mods is now on Flowplane. He already has multiple exclusives ready to go, including over an hour long director's commentary of his GameCube Joy-Cons video and a bunch of behind the scenes information. So if you love Shenk's content, but are left wanting by the big gaps between his videos, check him out on Flowplane for extra goodies. Now back to the video. This aluminum backplate represents the crossing off of every list item. We've done it. At this point, yes. So now we have everything sitting like a pile of meat in the case, loose. And once we put this on, then it'll all be mounted and secure. Then we can fill the loop and pray to whatever existence is beyond us that this thing actually still boots and works. So let's get this on. All right, ready? So I'm going to lift this up and then push this part in so then it fits. And then it slides right in. Okay, we've got FurMark going, Prime95 going. We're two minutes into this test and we do not have the fan set to 100%. So we're hoping that's going to be fine. If not, we'll try sending it to 100 and see how it goes then. And how loud it is. Yeah. 23 minutes in, temps have stabilized. Tyne, can you remind us what the numbers were before? The CPU max before was? So CPU max before was 68.8 degrees. Now it's 81.6. The GPU temp before was? 52 degrees. 52, the max now, 64. So hotter, but not technically throttling. The CPU could be cooler. Yeah. I wouldn't want to like daily drive at 82. But I'm pretty happy with the GPU temp at 64. That's not that bad. So let's wrap it up. Yeah, so let's restart it, go into the BIOS, crank the fan and see if it runs any better. It's been 20 minutes with the radiator fan max and we dropped 10 degrees. LTEstore.com, ladies and gentlemen. 70 degrees on the CPU and what is it? Bounced around 54 on the GPU. Wow. Damn. Not bad for so much power in such a little case. And what, 9.4 liters? 9.6. Less than 10. I can drink that in a day. Oh yeah. But this is a gaming rig, so let's play some games. I feel terrible that I missed all of this, but at least I get to see it now. Are you ready for this? I'm ready to feel greater. Oh my God, it's amazing. You guys did up the Astendo. What did you even do? Is this just the electrical tape? Oh. Oh. Sh** dog. Shut up. This might be the greatest retro-themed gaming setup of all time. No, I'm serious. What could be better? We've got the Astendo, like basically, how many of these even exist anymore? You know, rear projection ultra wide, the first ultra wide. We've got the one and only Hot Wheels PC. That's interesting. Well, it's Hot Wheels. Wait, the radiators. You guys managed to get everything inside? Holy crap. Is it ever? Can I open it up? It doesn't open up the old way anymore, does it? Well, the problem is you'll see that these are rivets and not screws. Uh-huh. Yes, I see that. And the reason for that was because it's so tight in there. Yeah. That if we use screws, we wouldn't be able to hold the nuts so that the nut didn't spin. We couldn't even put nuts in. It's nutless. No nut Hot Wheels PC. I have to game on it. Oh, okay. It's the actual Hot Wheels mouse. I was hoping we had a modern mouse with vinyl decals like you guys did on these. But wait, what? You guys spray painted an entire keyboard for this? Yeah, you didn't even take the keys off. Just went for it. I love it. Took me this long to notice though. So stealthy. This is absolutely insane. What could be more glorious? Oh, I see. Oh, I see. Oh, that's actually pretty sleek. Oh, my gosh. The only thing I've ever seen that gets close to this is Luke's fallout bomb PC. It's packed so tight. Front to back RTX 3090. Frickin flex ATX power supply. There's two of them. There's two? There's two. This may be the greatest computer in existence. What? You don't believe me? Fine. Show me a greater one. Prove it is greater. Is this custom? Did Shank do this? Well, this is my favorite Xbox controller. Is it mine? Oh, crap. Okay. That's fine. I would too. The maximum noise of it isn't even that ridiculous. To be clear, it's not quiet, but it's not loud in the ways that I might have expected. For example, those flex ATX power supplies are barely even contributing. It's just that knock to a air mover industrial PPC fan that we've got in there. Kids, can you say 130 FPS at whatever weirdo resolution this is? It looks like garbage because the image is so soft on this monitor, but it's running great. I was big into the just, you know, black frames around everything. No, dog. I want a blue, orange and yellow monitor now. There's just no other way to put it. This build absolutely slays.
