Alright, here's what I'm ordering I think based on all the helpful commentary:
RAM:
Crucial 184 Pin 512MB DDR PC-2700 - OEM - X2
Video Card:
ROSEWILL ATI RADEON 9800 PRO Video Card, 128MB DDR, 256-Bit, DVI/TV-Out, 8X AGP, Model "RW98PR-128D" -RETAIL
I'm going to pick up a Power Supply Unit at Fry's I suspect to make sure I get something that fits and that I can easily return it if need be.
Any chance I can get one final last pieces of commentary before I made the order?
