Good old UK
Yo. What you want is a baybus controller or something similar. If you're any good with a soldering iron, you could make up something yourself, with an LM317 variable voltage regulator, a variable resistor, and a couple of other components. That'd probably be cheaper, and the bits are available from a maplins store near you (I'm in England too). Of course, as you're an IT manager, you can afford a baybus right?... :D just had to get that in chap :p . I can bung you a circuit diagram if you like. Or you can do it the nasty way, with a rheostat (yuck) and have problems bunging on extra fans and stuff...
