What about a blue cube combined with something like this?
I do have extension cords, but really not keen. I mean, I'm already connecting an old Ps2 keyboard to a ps2 to usb converter, and now I still have to use another cable. Doesn't that just increase the chances of signals screwing up?
What horrifies me most, is if I go away from my computer, and five minutes later return to see the system messed up because the keyboard was sending trillions of keypresses in my absence.
