I remember seeing a keyboard mod where they took out the numlock/scrollock LEDs and hooked them up to LED strips for a desk light.
The bulbs run off AC power, but that is provided by an inverter which itself uses DC power. I doubt you'd be able to run cathode bulbs straight off mains power since despite the fact that it's AC, it's also a completely different voltage and most likely a different frequency as well compared to what the inverter produces. At the very least you'd need some kind of device to transform the AC power into something the bulbs can run off, and at that point you may as well just use a power supply to power the thing anyway.
