## Long description

The TACENS Mars Gaming MC-XO is an ATX mid-tower PC case that balances performance and a minimalist aesthetic. It supports ATX, Micro-ATX and Mini-ITX motherboards, houses a bottom-mounted power supply, and includes one preinstalled 120 mm FRGB rear fan. The case accommodates up to five 120 mm fans, CPU coolers up to 163 mm, and radiators up to 280 mm, while offering storage for one 3.5" HDD and three 2.5" SSDs. The design features dual seamless tempered glass panels for an unobstructed view of internal components and a full-length lateral ventilation grille called SIDECOOL to improve lateral airflow without altering the case’s clean exterior.
Advantages
The MC-XO delivers efficient thermal management through its SIDECOOL lateral ventilation and a dual-chamber layout that separates the power supply and storage from the main components for reduced heat accumulation and better cable routing. Frameless dual tempered glass panels provide durability and a clear view of installed hardware. Practical maintenance features include a magnetic top dust filter and a removable bottom filter, and the bottom I/O panel offers accessible connectivity with one USB 3.2 Gen 1 Type-A port, two USB 2.0 ports, and HD audio/microphone jacks.

Mid-range and high-performance gaming PC builds

How to use

Place storage drives into the designated 3.5" or 2.5" bays and route power and data cables through the dual-chamber layout to keep airflow paths clear. Install additional fans or a radiator as needed—top positions support 120/140 mm fans and the case accepts radiators up to 280 mm. Connect front I/O cables to the motherboard header for USB and audio functionality. Use the tempered glass panels to access internal components for assembly and maintenance.
Usage recommendations
For optimal cooling, pair the MC-XO's SIDECOOL intake with at least one front or top intake fan and maintain the magnetic top and removable bottom filters by cleaning them regularly to prevent dust buildup and preserve airflow performance.
