Jonsbo D300 black

A Mini Tower gaming case built around the “aquarium” concept. The model was launched by Jonsbo in 2024 and, among other things, stands out by supporting motherboards with back-connect layouts (when connectors and cables are placed on the rear side for an ultra-clean look in the main chamber). Front and side glass panels create a display-like effect, showing off components without cable visual noise—especially valuable for systems with custom cooling and RGB lighting.

Despite the compact Mini Tower category with dimensions of 460x236x421 mm, it fits GPUs up to 430 mm and CPU coolers up to 180 mm, surpassing many full-size cases in component clearance. The Jonsbo D300 ships without preinstalled fans, giving users complete freedom to choose a cooling setup for their specific needs. Ten fan mounting points offer exceptional flexibility: three side positions for 120 mm models, up to three on top with 140 mm support, a bottom combination to create positive pressure inside the case, and one rear exhaust position.

Liquid cooling support includes a 360 mm top radiator and 140 mm at the rear, enabling powerful CPU and GPU cooling in a compact form factor. A rigid 8 kg steel build enhances stiffness and reduces vibrations, the bottom-mounted power supply up to 200 mm includes a dust filter, and the hidden cable routing works especially well thanks to the motherboard’s back-connect design.
