I have been shopping for a computer to have at my new job. It needed to be a DP workstation, with plenty of RAM/HDD expandability. I would have loved a Sandy Bridge E Mac Pro. Alas, one does not exist, so I went through Thinkmate instead. Basic config of Thinkmate HPX XS8-2462: 2 x E5-2630s 128 GB (8x16GB) RAM -- another 8 free slots and expandable to 512 with 32 GB DIMMs, should the price ever fall and need arise. 1x1TB HDD -- Self install Ubuntu or maybe Biolinux (to give you an idea of what I do) as OS, 7 additional free drive bays. NVIDIA GT 520 -- Primary use of this machine will be in terminal anyway... Bought separately: 5x3TB HDD -- 4 will go into RAID5 (9 TB usable scratch space), one will go in my desk should a drive fail. ViewSonic VA2431wm 24" LCD Total system cost was just under $5500. The new 12 core 2.4 Mac Pro with 96 GB of RAM, 4x3 TB HDDs would have cost just slightly less (~$5200), while the 12 core 2.66 would have been substantially more (~$6500). I know its been well documented the speed improvements now available with other vendors and the frustration of those of us that would rather use OSX that need a workstation, but I thought I'd post this user's frustration that cost Apple a potential sale.
