This is a beast of a server.
Quad 550Mhz Xeons
3 Redundant 1150W PSUs
4250ES Raid Controller
System was a barebones machine that I fixed up. Ran CentOS 3.4 perfectly for months.
Originally asking $900, I am reducing my asking price to $600.
This machine is VERY large and VERY heavy. You can add up to 21 SCA80 hard drives, it uses the newer universal drive trays that also work in modern HP servers.
