PC case Sharkoon REBEL C20 ITX Black

The Sharkoon REBEL C20 ITX Black is a compact Mini-ITX PC case that combines a small footprint with a roomy interior. It supports Mini-ITX motherboards, SFX and SFX-L power supplies, and offers space for large graphics cards as well as compatibility with up to a 360 mm radiator. The case can be positioned vertically or horizontally and features perforated panels with dust filters for protected all-round air intake.

Advantages

The case accommodates very large modern GPUs while retaining a compact Mini-ITX form factor. It provides flexible installation orientation (vertical or horizontal), extensive cooling options including room for multiple fans and a 360 mm radiator, and modern front-panel connectivity with USB-C and TRRS in addition to standard USB ports. Perforated panels and dust filters protect air intakes without restricting airflow.

How to use

Install a Mini-ITX motherboard and an SFX or SFX-L power supply following the included manual. Mount storage drives in the provided 2.5" and 3.5" bays. Fit your chosen graphics card into the GPU slot; the interior is designed to accept very large cards. Configure cooling by installing fans in the available positions or mount a 360 mm radiator if liquid cooling is preferred. Use the front-panel USB, USB-C and TRRS ports for external devices.

Recommendations

For best thermal performance, combine front/side intake fans with rear or bottom exhaust. Use dust filters on intake panels and clean them regularly. When installing very large GPUs, ensure sufficient clearance for cables and cooling components, and choose an appropriate SFX/SFX-L power supply with adequate wattage for the chosen hardware.
