	Never had an issue with Gentoo on any of them. The SCSI and ether 
drivers were well supported.

I am not sure about the xx00 series, but you could hot swap PSUs in the 
xx50 machines.

Hmmm the SCSI card was onboard and you could get RAID by adding the 
memory dimm/unlocker doohicky if your system didn't come with it. We hit 
Ebay and picked up a bunch for cheap. Within a series the SCSI card was 
always the same other than maybe minor revision. Perc3i ver 3, ver 2, 
and etc in the 2600 and then Perc4i ver 1, ver 2 in the 2800.
	You'd never have an issue with an early rev or later rev having issues 
in any 2.6 kernel I ran.
