I dont know, DO i need 4gb+ for 64bit? To be honest i wasnt sure if i did or not.
There isnt much need to have any more than 2gb in reality, in this system, I cant imagine much work or heavy workloads hardly, if ever, So may opt for 32-bit to save some money - ty for the tip.
I can probably get his case / tower and cut $30 off the job, allthough im unaware of the specs, and its about 10 years old.. I guess its probably not going to be feasible to build the computer around the old casing, just to save myself $30 ish..
