Or for $200 you could get a Case+PSU (dunno how quiet), motherboard, CPU, and RAM that ought to best your current system in basically every way:

Add your own hard drive, transfer the DVD-ROM from your old system, and you're set.

Actually, I don't know if this would be better than his current system, merely b/c of the CPU- celeron (even dual core) I'm really leery of vs a full P4... unless they've done some serious work on celerons that I don't know about in the past few iterations.
UPDATE: I did some research, as I've always dismissed Celerons, and it seems that they changed the die and increased the L2 cache, which are promising changes. Does anyone know where there are comparisons of this new breed of Celerons vs non-Celeron processors?
