The Great Pyramid
Here's an interesting case built by polo360x, which first appeared over a year ago. According to this post, the actual chassis is 7.5 lbs. and is made of laser-cut, (very) high-quality black and silver aluminum. The base measures 19" x 19" and is 25" high. Inside the rig, you'll see an Intel Core 2 Quad Q6600 B3 overclocked at 3.15 GHz. It also has 4GB of memory overclocked to 1,066 MT/s, a Zotac GeForce 8800GT AMP! Edition graphics card, a 500W power supply, a 500GB Caviar WD 3 Gb/s SATA hard drive, and more. Check out the rig in action on YouTube.
