What's the easiest way to cleanly cut a small-ish piece out of a sheet of aluminum?

I'm repurposing an old computer case and need to make a new plate for the back to hold the I/O shield/port cover for the new motherboard. The piece itself needs to be 3"x9", with a smaller rectangular hole cut out of this piece. I picked up a few sheets of thin aluminum from Home Depot and was able to cut them up using a Dremel but the cuts weren't very clean or even. It turns out that I need thicker and sturdier material, so before I fire up the Dremel again and spend more time cleaning up the edges than I did actually cutting, I figured I'd ask if there was a better way. I considered shears but figured they'd warp the metal too much along the cut edges and I don't trust that I'd be able to create any straighter of an edge with those anyway.
