Here's another desk with a built-in, water-cooled PC. Apparently, Case Mod Blog member and modder USFORCES wanted more space on his desktop. To accomplish this, he decided to remove his tweaked Q9650-based system from its previous Thermaltake tower enclosure and integrate it into the right side of his desk.
Ultimately, he built an entirely new desk from scratch using 3/4" oak plywood sheets. He mounted most of the hardware behind the desk door, while placing the two BFG GeForce GTX 280 H2OC graphics cards in an area just under the desktop, highlighted with UV and green LEDs. USFORCES also built a special dual-loop acrylic reservoir just for this particular setup.
