You might check the studs in the new case that you used to screw the motherboard in place with. Is it possible that one of those studs is under the motherboard grounding it out? If you put a stud in the wrong place and lay down the motherboard, you won't see the error if there isn't a hole for a screw.
You might also try another power supply--some of these $19 dollar cases have a power supply that say 300 watts and I'll bet that they're really about 180 watts.
