Computer geeks spend ridiculous amounts of money on high-end rigs all the time, but one digital electronics engineer from Cambridge, England, poured a small fortune into building a giant computer that he only uses to play Tetris.

James Newman’s supercomputer took five years to build, cost over $53,000 and takes up an entire room, yet it is a million times slower and has a million times less memory than a typical desktop. That’s because it’s actually just a mega microprocessor. “Computers are quite opaque, looking at them it’s impossible to see how they work. What I would like to do is get inside and see what’s going on,” Newman explains on the Megaprocessor project website. “Trouble is we can’t shrink down small enough to walk inside a silicon chip.
