I just recently purchased a computer case that has built in metal risers. With the motherboard installed on top of these risers it fits pefectly and matches up with the I/O cover. If I use the brass risers it lifts the motherboard to high to connect to the I/O cover. I tried installing an old motherboard that was working previously in the case and it no longer powers on. Green light comes on but no power. The power supply still will power up other motherboards that I have. I'm assuming I shorted the board. I have a new motherboard that I would like to install in this case but don't want to risk shorting this one. Has anyone built any computers with these type of metal risers built in to the computer case? Do I need some plastic stand offs or what? Please help.
