Couldn't quite go through with the iMac. Instead, I'm replacing most of the guts in my current machine (Athlon 64 X2 4400+, BFG 8600GTS, 2GB RAM, and a fresh motherboard) and running with that. Maybe some other time I will get a new Mac, but now is not that time I guess.
EDIT: back to more technical (and interesting, to anyone not being me) subjects soon. :-)


(I seriously need to get mine tuned up - it's been gathering dust for over three years, sigh)
I, too, am going your route.
