Thermaltake today announced the Core X31 Tempered Glass Edition (model: CA-1E9-00M1WN-03), a variant of the Core X31 mid-tower chassis featuring a tempered-glass side-panel, replacing the acrylic panel on the original. The clear panel covers the entire area of the side panel, letting you show off your gear. Measuring 250 mm x 511 mm x 497 mm (WxDxH), this is one of the wider mid-towers you'll come across, with the extra width being distributed between more "crawl-space" behind the motherboard tray for better cable management, support for larger 200 mm-wide fans along the top and front panels; and additional height clearance for the motherboard tray, letting you accommodate tall CPU air coolers, or an additional graphics card along the plane of the motherboard, using an included PCIe riser. The Core X31 Tempered Glass Edition features a flexible design, with detachable drive cages and support braces, letting you accommodate heavy liquid-cooling gear, such as pumps, reservoirs, and tubing. Storage areas include two 5.25-inch drive bays, and three 3.5-inch/2.5-inch drive bays. Cooling includes support for one rear 140 mm fan, two top 200 mm (or 3x 140 mm or 3x 120 mm) fans; one 200 mm front (or 2x 140 mm or 2x 120 mm) fans; and two 140 mm (or 2x 120 mm) bottom fans. Each of these fan slots can hold radiators of the corresponding size. The company didn't reveal pricing, but we expect it to be a small premium over the original's $130 price.
