Is it a flux capacitor? A futuristic exercise bike? An electronic sculpture made from salvaged water treatment components? Nope, it's the DarwinMachine Hammerhead Computer ($2,950). Inside its insane case lies a powerful blend of components, including a 2.93 GHz Core i7 CPU, 4GB of RAM, a 40GB SSD, a 1TB hard drive, a second drive bay, an optical drive, an nVidia ENGTX550 TI graphics card, and a copy of Windows 7 Home Premium. Good luck finding furniture to match.
