case mod

1. Originally a kind of hardware hack on a PC intended to support
overclocking (e.g. with cutouts for oversized fans, or a freon-based or
water-cooling system). 2. Nowadays, similar drastic surgery that's done just
to make a machine look nifty. The commonest case mods combine acrylic case
windows with LEDs to give the machine an eerie interior glow like a B-movie
flying saucer. More advanced forms of case modding involve building machines
into weird and unlikely shapes. The effect can be quite artistic, but one of
the unwritten rules is that the machine must continue to function as a
computer.
