It won't win any design awards with its 1960s surplus power and reset buttons and scrounged LEDs/parts of an AT case and ATX power supply. However the whole thing cost me $10 for the microATX power supply and a day's worth of futzing around, and it was entertaining. Now, it waits only for MOS 1.5
The long term plan is for this to go inside a much more elegant case, but that will take time to build so for now, this is it. I just didn't want the graphics card flopping around while the machine was on..
