Cooltek rolled out the GT-03, an ATX mid-tower case that looks heavily inspired by some of the recent works of SilverStone, such as the Raven RV-05. Where it falters is the use of SECC steel and matte ABS plastic, instead of aluminium. Measuring 510 mm x 200 mm x 460 mm (DxWxH), the case dry-weighs 5.2 kg. Its front panel features a 'shield'-shaped cover over its three 5.25-inch drive bays, of which two are usable, with the third being an exposed 3.5-inch bay with a clip-lock protrusion of the door. Other front-panel features include a SATA drive dock, two each of USB 3.0 and USB 2.0/1.1 ports, and standard HD audio jacks.

Internally, the GT-03 has room for CPU coolers as tall as 152 mm, and graphics cards as long as 300 mm. Internal storage areas include three 2.5-inch, and four 3.5-inch drive bays. The motherboard tray has cutouts at all the right places. Installation, for the most part, appears tool-free. Ventilation includes two 120 mm front intakes, a 120 mm rear exhaust, and two 120 mm top exhausts. The case is now selling for 44.99€.
