Watch the power supply - more aged units sometimes don't give out the right voltage (should be +12V, +5V and -5V) and will result in newer, faster drives refusuing to start. >Will the machine run with "passive cooling" (fan disconnected)?

The heat generated by a 25MHz 040 is enough to make you smart if you catch your finger on it while it's running without as heatsink. The hard drive will also get very hot. With the lid removed you will gain a bit of heat dissapation. My advice (and I have done this myself - I used to have a similar setup in a filing sized deep desk drawer) is that you should fan ventilate it somehow, oir fit a large passive heatsink on the 040(something about the size used to cool Pentuium 150 CPUs is about right, with the fan removed) and do not cover the hard disk.
