The Xigmatek Cubi M is a mid-tower M-ATX gaming case in a sleek black finish, built for a compact but capable gaming build with six pre-installed ARGB fans. An intelligently designed interior supports high-performance components with multiple fan mounting options, superior ventilation and simplified cable management. It takes motherboards up to M-ATX and Mini-ITX, with room left for future upgrades.

Panel installation on the Cubi M is designed to be effortless, so building inside a compact chassis does not begin with a fight to get the sides off. That matters more in a smaller case, where every cable route and drive mount is reached through an opening rather than around one.

A tempered glass panel shows the interior and the six ARGB fans, and it is built for easy access rather than being bolted permanently in place. Removing it is the first step in any upgrade, so a panel that comes away cleanly is what keeps a drive or fan change to a short job.

The Cubi M uses an advanced airflow and ventilation system with fan mounting at the top, the motherboard panel, the bottom and the rear. Pulling air in low and at the side and exhausting it at the top and rear is what stops a compact chassis trapping heat around the graphics card.

Power supply size is limited to 200mm in length, which covers standard ATX units and many higher-wattage supplies. In a compact chassis the PSU depth decides whether the bottom fan positions stay usable, so check the supply length against that 200mm figure before ordering one.

Maximum VGA length is 358mm, which fits most dual-fan and many triple-fan cards despite the compact footprint of the chassis. Length is the first specification to check on a smaller case, and 358mm covers considerably more than the M-ATX form factor usually suggests it would.

CPU cooler height support runs to 165mm, which accepts most large tower air coolers rather than restricting the build to a low-profile unit. Getting a full-height cooler into an M-ATX chassis is what lets the Cubi M run a high-performance CPU without moving to liquid cooling.

The Cubi M supports M-ATX motherboards and takes Mini-ITX boards as well, which is the pairing most compact gaming builds are based on. Choosing the smaller board sizes is what frees the interior volume that goes to the six fans and the drive mounts instead of to bare tray area.

The fan cooling system supports three 120mm or two 140mm fans at the top, two 120mm or two 140mm on the motherboard panel, three 120mm or two 140mm at the bottom and one 120mm at the rear. That is substantial mounting capacity for a chassis of this size, and six fans arrive already fitted.

Liquid cooling support covers a radiator up to 360mm at the top, up to 240mm on the motherboard panel and up to 120mm at the rear. A 360mm top mount is unusual in an M-ATX chassis, and it means a high-capacity AIO cooler does not force a move to a larger case.

The Cubi M supports two 3.5-inch hard drives, so mechanical bulk storage still has a home in a compact build. Two bays is enough for a large media or archive setup alongside the SSDs, without a drive cage eating into the airflow path the six fans depend on.

Three 2.5-inch SSD mounts sit alongside the hard drive bays, taking the total drive count to five. Keeping the SSD mounts separate means a solid-state drive never consumes a 3.5-inch bay, so a boot drive, a games drive and a working drive can all be fitted at once.

The top-mounted I/O panel carries a power button, a reset button, an HD audio jack, two USB 2.0 ports and one USB 3.0 port. On a compact case that usually sits on a desk, having the ports on top puts them directly in reach rather than around the back of the chassis.
