I ordered a 3.0 GHz mac pro, it will arrive late this month (BTO with the ATI card). While I'm waiting, I took the minimum hard disk (160 GB) and memory configuration (1GB). I already have a 750 GB SATA drive waiting to go, and I want to get at least another 1GB RAM. At the time nobody really had adequate RAM for the Mac Pro due to the heatsink requirements. I haven't seen any updates lately, so... Does anybody have Mac Pro-friendly RAM that has a company track record of being reliable with Macs yet?
