He put his computer desk inside. He got tired of it within a few years and then used it as a garden shed for a while.
That case was odd because the wave shape was quite unnecessary. I guess someone told the designer "design a case, but don't just make it a rectangular box." Someone at Tera mentioned that it cost $60k to make. Presumably that's for the first one and subsequent copies were cheaper (I hope.) Inside the plastic shell was an extremely sturdy metal frame. The sides of the shell were held in place by electromagnets in the frame that were powered when the thing was plugged in. So the case had one power plug, and the machine had its own separate power supply. The machine itself used a lot of power and I think it needed more than just an ordinary 120/240V connection.
