My suggestion is only a suggestion. Nontroppo, get the RAM and another BIG hdd (You'll have a free IDE channel for another drive or DVD unit :) ) Off load some of the apps and data to the bigger HDD and get Win2k or XP and install that in the space freed on the orignal 10 GB drive (Dual boot anyone?) My computer (see Msg 5) used a lot of components from my old PC.
