Heh, this WinXP install has survived past 4-5 HDDs (one or two of them had errors the repair shop couldn't fix that i managed to myself) and several years so far , and this with hard use, almost 24/7 intended up time (i don't shut down when i go sleep or leave the house, but eventually it might crash when i'm not paying attention, or the light might go out), with porn browsing in unknown sites, downloading and running of cracks and keygens etc and countless programs from all sorts of sources :P
