Yeah, I built this one. I just don't have a spare mobo or power supply. Hopefully it's just the power supply, but even if it is, I also have to track down what caused the short. I recently switched cases to one with more fans, which I guess would increase the power draw, but it seems like it would be such a small increase. I'll take it to a local shop today and see if we can test the PSU. Hopefully that's all it is.
