I've managed to beat down the urge to get new/different hardware into the house recently, since we have enough older stuff that I haven't quite exhausted all of them for my 'upgrades'. (It's still an upgrade if you move from older stuff to old but less old stuff.)
I did have a stretch of bad luck with this tower I bought used--tried to use it but it just kept crashing. I think it's a bad video card, but I'm not going to chase my sunk costs on that one.
