Racking Mac Pros
It's really kind of mind-boggling that Apple makes and sells the Pro, which can be upgraded to a really nice high performance GPU workstation, but then doesn't sell the same hardware in rack mountable forms for clusterable computing.I'm sure they've performed some kind of market analysis for this, but there's enough differences between OSX and Linux solutions that for people who use HPC solutions (a growing market) a cleaner path from OSX to HPC would be very helpful.
