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).
That, IMHO, is the best way to go. Another way, if the HW is available, is to test it with a Live CD for CentOS, before purchasing, to see if CentOS will run properly on the HW.
