That's precisely the point - except for the 8 Gb of RAM.
Linux Server can turn a fairly plain-vanilla motherboard into a stable workstation capable of supporting reasonable operating RAM. Try WinXP, Windows Server 2003, or even as it happens - OpenSuse 10.x - they all splutter with the vary large RAM. OpenSuse is ok up to around 4 Gb, but struggles over that for CFD work, which is very memory-interactive.
Wasn't too long ago that many University mainframes didn't allow this much RAM per user.
