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.<p>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.
