Jonsbo Z20, black

The Jonsbo Z20 is a compact M‑ATX chassis that packs roomy hardware compatibility into roughly a 20‑liter footprint. Designed for Micro‑ATX or Mini‑ITX builds, it offers a carry handle and a small footprint while still allowing installation of long GPUs and a 240 mm top radiator when components are chosen with clearances in mind.

Z20 provides flexible layout options: support for graphics cards up to 363 mm, CPU cooler height limits of 164 mm (Intel) / 163 mm (AMD), and compatibility with ATX (with length restrictions) or SFX/SFX‑L power supplies. Cooling options include twin 120/140 mm fans top and bottom plus a rear fan; front I/O has both USB‑A and USB‑C. Those features suit compact gaming rigs, portable workstation builds and LAN‑ready systems where balance of size and performance matters.
