A cool item for PC enthusiast!! I built my dream PC 15 years ago. Over the years I upgraded it with premium components to keep it snappy but Microsoft finally made it obsolete by not offering an upgrade path to Windows 11 on the motherboard. I saved all the packaging and accessories for all of the components, and I'll be listing them all. Check my other listings for compatible components.

Item comes with the original packaging.

Pristine condition for a 15 year old case. It's missing one front bezel so I'm throwing in a memory card reader to cover that bay. It's also missing a couple back bezels. I'm throwing in all the screws I took out of it, whether or not they came with it, I do not know.

Great for water-cooling and has 12 drive bays.

The Twelve Hundred is an evolutionary improvement that capitalizes on the original design and adds even more for a design that can take whatever you throw into it. Even the largest 10.5” graphic cards like AMD’s Radeon HD 3870 x2 and Nvidia’s 9800 GX2 fit into any of the 7 expansion slots within its cavernous interior without limiting hard drive placement within any of the 12 bays. Mini ITX, Micro ATX or standard ATX motherboards likewise fit with ease.
A pair of three-speed 120mm blue LED fans exhaust heat out the rear of the case while a 200mm fan does so through the top. The speed of the fans, can be controlled from the outside of the case. Space and mounting points are provided for two more 120mm fans – one in the middle to cool the CPU or graphic card, and another bringing air in through the side panel to cool the expansion cards. Knockouts for liquid cooling systems are built in as is a platform for a reservoir or pump.
Because excess heat will kill any system, the case is designed to maximize cooling. The perforated front bezel offers maximum air intake by the trio of 120mm blue LED fans that pull air through the washable air filter. The front panel is finished off with top-mounted I/O ports for easily connecting an eSATA and a pair of USB 2.0 devices along with HD audio inputs and outputs.
