Well, I'm using a (cheap) sampling wattmeter, which is supposed to
sample instantaneous voltage/current around 1k/sec, and it says that I'm
using around ~60W with my setup (no monitor). I have no reason to
disbelieve it. Yours sounds on the high side, as I've also got a 3.5"
disk and a DVDROM drive.

Heh. My AMD Athlon XP 2100 sucks up around ~290W, counting an old
17" monitor (768MB PC2100, 2 HDs, CDRW, DVDRW, GEForce 4 Ti200, TV card,
LAN card, & four fans ;-). I wish my "space heater" would use up only
150W. ;-)

How warm (roughly) is yours running? I've got mine stuck in an
aluminum case, and the air being blown out is somewhat warm. I haven't
bothered to see where the heat is coming from, but I'd be pretty wary of
removing a CPU fan (although your proposed setup sounds fine).
