>BTW, it was installed in a bar, next to the espresso machine. You should have seen the PC after two years of intensive use there - we just couldn't clean it up. All the kitchen and coffee vapors have condensed on the inner side of the housing. Though, maintainance was fun - sitting on a bar stool and working :)

Most of my dealings are with a wholesale beauty supplier. Try maintenance after all their hair/nail chemical crap, food, coffee, drinks, dust, cigarette smoke and ashes, etc., have accumulated in and around their equipment. Totally disgusting.
