Thermaltake today introduced the S250 TG ARGB, a mid-tower case with a unique expansion slot feature, and the ability to mount large 420 mm radiators. The case comes in two color variants—black and white. It is characterized by a large mesh intake along the front, with three pre-installed 140 mm ARGB-illuminated fans. These can make way for a large 420 mm x 140 mm radiator, or something smaller. The case features a conventional horizontally-partitioned layout. The upper compartment with the motherboard tray offers room of up to 40 cm for graphics cards (with nothing in the way, or at least 32 cm with a radiator in place); and CPU coolers up to 16.5 cm in height. The PSU bay in the bottom compartment has clearance for 22 cm.

Right next to the motherboard tray are two 120 mm fan mounts that point toward right side panel, which is perforated in that area. You can mount another 240 mm x 120 mm radiator here. The top panel has an additional three 120 mm vents, and a 360 mm x 120 mm radiator can be mounted here. A unique aspect of this case is that its 7 expansion slots can be rotated 90° to create vertical slots, so you can vertically mount a graphics card that's as thick as 5 slots (think ASUS x Noctua RTX 4080). The drive cage in the bottom compartment holds two 3.5-inch drives, or two 2.5-inch drives, there are two additional 2.5-inch mounts. The left side panel is made of 4 mm-thick tempered glass. Front-panel connectivity includes two type-A USB 3.2 ports, and a 4-pole headset jack. The case measures 218 mm x 462 mm x 490 mm (W x D x H). The company didn't reveal pricing.
