If you need parts,,,especially,like more RAM or a video card or better fans and filters or a new cheap better tower case(in SJ, Fry's has a good selection to see up close and low prices,like $50 for an AirMaster),,,
or accessories,,,like a back-up hard drive, (i have a Buffalo next to my monitor and printer, above the tower at my feet on a shelf).
or a computer, maybe.
