if it was a memory problem would it start up and run when it's out of the case?
Not sure, depemnds on what was causing the memory problem. If it was a flaky connection or a short under the socket on the MB in the case then maybe. The whole reason I was thinking memory was the comment that you got beeps when you took all the memory out. If that was the case and you didn't get beeps when the memory was in it strongly suggests that putting the memory in stopped it from the POST operation (Which is where the beeps come from)
If it consistently runs when outside the case I would look at the MB/Case interface. do the mounting screws cause some kind of short? Does mounting the MB in the case cause some kind of deflection that would break a signal line in the MB (do you have to force it in place or will all the mounting points line up if you just gently lay the MB in place? Is there something under the MB that would short or cause a bad signal path (any of the solder points on the bottom extend lower than the others?, are there wires laying under the MB that could be a short or signal path?) In general look at what is different in the works/doesn't work condition (Yea I know that is the obvious comment ) And of course I can always fall back to the comment I made a while back (I'm not sure whose problem it was) "When nothing makes sense look at the power" Are you using the same power supply when outside the case?
