You could also put a couple of Athlon 2000s on that board. It was
actually made with AMD in mind, specifically MP processors, but in
actual fact there is very little difference between the Athlon and the
MP. The Athlon has a config turned off, but if you know what you are
doing, apparently you can switch that back on too, if you need it.
That would really make that board hum.
