EDIT - I resurrected one of my old PC. However, I do not know what to do with it. It has an P4 (775) clocked at 2.66GHz, 768MB DDR, 7300LE PCI-E, and a 40GB IDE drive.
I usually just put old computers out in the kennel office and use them for documents and videos and internet for when I'm out there bored. Back when I lived at my old place I donated an old computer to the library I worked at as the IT guy since I had no use for it and they were still using windows 95 and 2000 on their only 2 computers
I got a free NZXT Beta Evo in the mail today from 3DGAMEMAN's NZXT giveaway. I'm not sure what to do with it. I know for a fact I won't be replacing my current case with this. Seems like a solid case with some good features.
Not bad for a free case. Next time you upgrade your system stick your old parts in it for a backup gaming rig.
I'm probably going to be replacing my Antec Quattro 850 power supply pretty soon. I want something quiet, 80mm fans are not good at that while moving a reasonable amount of air.
