|Behold, the Toolbox PC before it had an operating system.|
I had built a few PCs before this one, so I had a pretty good grasp on it. But those PCs were designed to stay in one place. At the time, I was going on extended trips and thus didn't have access to my Steam library. At first I brought an Xbox 360, which was fun, but PC games allowed for so much more.
So I needed a PC that I could take with me that would withstand a bit of abuse. I expected this thing to be dropped a few times (and it was). I spent a few weeks searching the Internet for PC cases built for abuse and nothing at a reasonable cost turned up. What I did find were some interesting custom cases, but they too were either cost prohibitive or designed more for style than utility.
Then the idea hit me: the Toolbox PC. I could get a rugged toolbox built with strong materials and add shock absorbers to the components.
