Cooltek launched the UMX1 Plus premium mini-ITX chassis. Available in a standard and windowed (UMX1 Plus-Window) variant, the case comes in black and silver color options, with brushed aluminium panels decking it. The windowed variant features a tinted acrylic sheet entirely making up the side panel. The aluminium panels of this case are a healthy 2 mm thick, while its SGCC steel frame is 0.8 to 1 mm thick.

Internally, the case has a typical tower-type arrangement, but with a standard ATX PSU bay towards its front side. The case has room for a mini-ITX motherboard, a dual-slot graphics card up to 270 mm long, a CPU cooler up to 130 mm tall, and a PSU up to 160 mm long. Drive bays include one 3.5-inch, and two 2.5-inch. Ventilation is care of a 120 mm top exhaust, and an 80 mm rear exhaust, with passive intake vents at the bottom. Measuring 160 mm x 300 mm x 345 mm (WxDxH), the case dry-weighs about 3.2 kg. Cooltek didn't reveal pricing or availability information.
