Well what I posted was both a joke... and based around fact.
My battery for the bios should be fine as the computter has only been turned off for perhaps 96 hours total in the 3+ years after I built it.
On the other hand my 5 year warranty HD has had 6 days of SpinRite 6.0 run on it to keep it from dieing (3 days last year and 3 this year) and is down to 90% life...but I work two pvt torrent clubs 24/7 and beat the hell out of it.
