Compact 9.9 Litre ITX Chassis

The Mechanic Master C24 is a 9.9 litre Mini-ITX case finished in yellow with a side window. It accepts Mini-ITX motherboards up to 172 by 172 millimetres, SFX or SFX-L power supplies up to 100 millimetres long, graphics cards up to 245 millimetres long and CPU air coolers up to 135 millimetres tall. A 120 millimetre radiator can be fitted for liquid cooling.

Suited for Portable High-Performance Builds

Builders who want a lightweight, handle-equipped chassis for dormitory or mobile-office use will appreciate the integrated aluminium carry handle rated for 30 kilograms total weight. The case supports three expansion slots, though graphics cards thicker than 40 millimetres block the bottom 3.5 inch drive bay and 120 by 25 millimetre fan positions. Buyers needing ATX power supplies, larger motherboards, 240 millimetre radiators or longer graphics cards should consider a bigger enclosure.

Thermal Behaviour Under Sustained Load

Airflow relies on a single rear 90 by 25 millimetre fan plus optional top and bottom configurations of either two 80 millimetre fans or one 120 by 15 millimetre fan on top and either two 80 millimetre or one 120 millimetre fan at the bottom. With only one exhaust fan fitted by default, sustained workloads on high-end components such as RTX 5060 Ti or 5070 class cards paired with 245K or 9600X processors will depend heavily on the user adding the optional fans to maintain acceptable temperatures.
