Well its nice to know my PC is animal friendly!!... After opening my case to fit a new HSF, I was surprised to see (well it made me jump!.. in fright at 1st) a spider crawling across the inside of my case. How the hell the 4 case fans didnt suck it out or blast it to bits I'll never know!.. but it seemed to be making a home for itself!! I dont think it had been in there long as there were no webs anywhere! Freaky!!
