But I don't want to get into the situation above, where I purchase NEW hardware, and CentOS doesn't like it, and furthermore the resolution is elusive.
What is the best HW environment for CentOS? Brand, MFG, chipset rev, and so on....
Easiest is to buy from a vendor that can test on your OS of choice, there are lots of vendors out there that can do it.
Two such companies I have bought from that do this include http://www.siliconmechanics.com/ (HQ in Seattle, WA area) http://www.asaservers.com/ (HQ in San Fransisco, CA area)
Both specialize in Supermicro/Tyan-based systems(as to most other "whitebox" vendors).
