Hello all! if you remember me, i purchased that dell system, thanks for all the info! anyways, it came with 512 MB of RAM. However, if I wanted to upgrade that, can I just go on ebay.com or something, buy 512 MB of RAM, open up my computer, stick the long skinny thing from ebay into my computer, and boom, it goes faster? and i got over 1 GB of RAM now? any info and help would be great, and general price ranges or better sites to purchase. THANKS!
