I'm wondering how much you guys think I can get for my Dual G4, as it might be approaching upgrade time. Its a Dual 533 model. It has 1 GB of RAM, stock 40 GB Hard Drive, 52X CDRW in the optical bay and a slot load DVD ROM drive in the zip bay (custom mod). It has a 64 MB GeForce 4 MX. I think thats the full specs. I have a 256 DIMM I plan on throwing in there next time i shutdown too, so the total will be 1.2 GB. What do you think?
