Some tips:
Buy a big fucking Power Supply. Get an Enermax (best out there in my opinion). I'd get a 400 watt or above if you can afford it.
The "plate" you're talking about comes with your new motherboard. It's called an I/O Plate, and they snap into most ATX cases with easy. Just snap the current one out, and pop the one that comes with your new mobo in. Problem solved. No Dremel necessary
