I have a extra desktop, dell to be exact, laying around that hasn't been in use for a long time. I was thinking about holding on to it so when I move out next year I can use that as well as my laptop. But since it hasnt been in use for awhile and its a couple years old I know some parts of it is old and probably slower. So I was wondering if you guys think I should just buy some replacements parts off newegg and put them in there to make it fast and better or can that not be done?
