Geeek has officially launched pre-orders for the Exo 1, an open-air microATX PC case that doesn't cost an arm and a leg. The new case is effectively an acrylic motherboard tray attached to a baseplate with attachment points for auxiliary hardware, like PSUs and cooling. The Exo 1 is available in both black and white color options, and Geeek also sells an optional PCIe 4.0 riser cable, which will set you back an additional $20 over the $69.99 pre-order price for the case . Geeek plans to start shipping those pre-orders on February 12, 2026.

Like many open-air cases, there aren't that many limitations when it comes to compatible hardware. For starters, there is no side panel, which means no tower air cooler height limitations, although it is technically limited to 240 mm AIO radiators, and using the vertical GPU mounting does limit you to low-profile coolers, thanks to the motherboard's position. There are also no additional fan mounting points aside from those used by the AIO radiator. Geeek recommends GPUs no longer than 335 mm, and says that GPUs up to four slots are supported. The Exo 1, being a compact case, measures in at just 400 × 185 × 315 mm, and it supports ATX, SFX-L, and SFX PSUs.
