Even if I had glued most of it, though, I'd still have needed some screws to hold the components in place and to open the case for maintenance.

Here's the case with the first pass on the components installed. Note the handle on top of the case for carrying it to LAN parties.

The two black strips you see on the side of the case (in the middle of the photo) are velcro. A similarly-matched pair of strips on the bottom of my keyboard allow it to stick to the side of the case when transporting it to LAN parties. Combine that with a handle on the top of my monitor, and a small backpack for cables and mouse and such, and I've got a system that takes only two hands to carry into the LAN party.

That's a single trip in from the car, people. For those who do LAN parties, you know what I'm talking about. There's something particularly nice about parking, grabbing your stuff, locking the car, and walking in. No going back out to the car for a second trip.
