Compact 9.9L Mini-ITX Chassis

The Mechanic Master C24 is a 9.9-litre Mini-ITX case built for users who need a small, portable desktop enclosure. Its aluminium and steel construction includes an integrated carry handle rated for 30 kg total weight. A side window panel is fitted as standard. The chassis targets dormitory setups, mobile offices and anyone moving a full build between locations.

SFX PSU and 245mm GPU Clearance

The case accepts an SFX power supply up to 100 mm long and graphics cards up to 245 mm in length. CPU air coolers up to 135 mm tall fit underneath the top panel. A single 90 mm rear fan is pre-installed; the top panel takes two 80 mm or one 120 mm slim fan, and the bottom panel mirrors that layout. A 120 mm radiator can be mounted for liquid cooling. Three expansion slots are available, though a GPU thicker than 40 mm blocks the bottom 3.5-inch drive bay and bottom fan positions.

Handles 245K and 9600X Class Hardware

The internal volume accommodates mainstream ITX motherboards up to 172 mm square and the component limits above, allowing builds around current high-performance desktop CPUs and mid-range RTX graphics cards. Storage is limited to 2.5-inch drives when a thick GPU or bottom fans are used. Builders who need ATX power supplies, 240 mm radiators, full-size GPUs beyond 245 mm or multiple 3.5-inch drives should look at larger chassis.

Questions about this item

How long a graphics card fits inside the 9.9 L chassis?

The case accepts cards up to 245 mm in length and 135 mm in width; anything thicker than 40 mm prevents a 3.5-inch drive or 120 mm bottom fan

What temperatures and noise should I expect when the system runs all day?

A single rear 90 mm fan and optional top or bottom 80 mm or 120 mm fans provide airflow; noise and heat depend on the CPU cooler and GPU you choose

Which power supply and motherboard must I already own for this build?

You need an SFX or SFX-L power supply no longer than 100 mm and any Mini-ITX board within 172 mm × 172 mm
