Go to NewEgg. Start with a tyan single CPU server board with integrated graphics. Add an Opteorn 140 or 240. You're at about $500. Use the other $500 for a case, memory, hard disk, etc. and crt. Load SuSE for AMD64 on it.
Voila! A $1,000 opteron system, complete with 64-bit OS, monitor, and a surprisingly large number of applications.
The computer being offered is intended for an employees home use. So your suggestion is to get a low end Opteron with low end integrated graphics, most likely minimum memory, a small hard disk, a minimal monitor, with an operating system that's in the minority, and applications that are mostly not used in a home scenerio. That doesn't make sense to me.
