Heh, amen.
I had two machines, one which had a broken powersupply but ha dTV input (6200, 75MHz 603 machine) and one that was ok (a 630, 33MHz 68040 machine) . I built a new powersupply, and decided to put it in the 630 (ended up with a lot of case-modding... not too pretty). So I had to swap motherboards and harddrives. Mobo is dead easy, harddrive takes about an hour :-)
