I just doped up an Ikea PS Laptop Workstation with some cork lining on its interior surfaces. Doesn't interfere with door operation at all, and makes it look about 1000% nicer. Plus gives some shock-absorption for the laptops when being placed onto the desk panel. Not sure if this qualifies as much of a hack, but it's a nice touch to spruce things up a bit.
