For the case, I decided I wanted to have something that was original but still looked good, whether through modding or building from scratch. I originally thought of building the case out of PVC since it'd be very easy to work with (connectors only need PVC glue to fasten and the pipes could be easily and quickly cut with only a handsaw, also much easier to drill into). I used to work at installing irrigation systems for houses and businesses during the summers while in college and we used a lot of PVC tubing.
During one job, I built a large support system that a submersible pump was connected to. It was set up like a sled so that the customer could pull it to the pond to pump water to the sprinkler heads. I kept thinking of other ideas but it kept coming down to the PVC or a suitcase mod. I decided on the PVC since I had already seen a few of the suitcase mods, but then while at Home Depot I saw the copper plumbing pipes and thought, that's what I need to build my case out of. The structure would be the same as that of my PVC idea, but copper would ground my motherboard whereas PVC case would not. Also, you can't beat that copper shine. Finally, building the case out of copper would be that one last excuse for finally getting my cordless Dremel, and a butane blowtorch (which also does a very good job at lighting charcoal for cooking out).
