i saw the cube just lyin at my work last month and asked if i could take it but the manager said no and said he'd sell it to me for $200 w/o the power supply. i said no. after a 4 weeks past by the cube was still lyin there on the floor. well, my manager was in a good mood one day and i told him i would give hime $50 for it and he told me just to take it. wahoo! well i set everything up, but there is a very high pitch noise that seems to be coming from the fan. is there supposed to be an annoying fan noise on the cubes or is it something i have to fix?
