I have a nice Dual 3GHz Xeon, but those Opteron systems (246/248 especially) are very appealing. Don't pass them up just because you can't run a 64-bit Windows on them yet!
Oh and be sure to check out the forums on 2cpu.com, especially for help on making your system QUIET. The fans that come with retail Xeons are extremely loud.
