In all seriousness though, if this is the SFF, they use a laptop drive. Full size towers use a normal DVD drive. To find the voltage on that thing, just cut the wires, strip some jacket off, and attach them to a voltmeter. Once done finding voltage, clip off a SATA, Molex, or Berg (*shudder*) connector that has the right voltage, solder ends together, and voila; working DVD drive!
