Don't forget that the uber hacker would have a binary clock (And, yes, I have a binary clock, but I can't be bothered to set it, so all of the lights just flash in unison, sort of its way of the flashing 12:00.).
Their machine would have to have lighted fans. And, of course, they'd have to have a couple of lighted muffin fans on the desk, too, to keep them cool (Forced air cooled processor; forced air cooled hacker.).
A true uber hacker would have an information panel connected to their machine to relay critical information, regardless of whether that critical information is the time of day, the machine registers, or a sale ad for the pub down the road (And, yes, I hacked OS/2 to display the time of day on an IBM 9595's information panel display.).
Headphones? No, of course not. Rather, multiple subwoofers mounted all around the operating position. You don't want to just hear the sound; you want to feel it.
Come on, y'all. Help me out here. What other accessories would a uber hacker have?
P.S. I'll get my coat; It's the one with the punched cards in the pocket. Don't trip over that stack of magnetic tape reels, nor 14-inch drive platters.
