Manufacturer description

The Mars Gaming MC300 is a Micro ATX chassis built around airflow and visibility rather than bulk. A TOTAL-MESH front grille feeds three pre-installed FRGB fans, and the triple front/rear ventilation layout pushes air across your GPU and VRM zone without you buying a single extra fan. The fixed-RGB lighting runs a constant color flow through those front vents, and the tempered glass side window puts the whole build on display. Inside, the MC300 takes MicroATX or Mini-ITX boards, mounts up to four 2.5-inch SSDs and two 3.5-inch hard drives, and supports a 120mm liquid cooler if you want to…
