help Jonsbo U4 Plus FAQ

Is the Jonsbo U4 Plus really a Mini-ITX case?

No. Jonsbo lists the U4 Plus as a compact ATX case supporting ITX, Micro-ATX, and ATX motherboards, so it is larger than a Mini-ITX-only enclosure.

What is the Jonsbo U4 Plus made from?

The U4 Plus uses an aluminum-magnesium alloy exterior with a brushed metal finish. Its compact ATX layout is aimed at builders who want a smaller case without giving up standard ATX motherboard support.

What cooling design does the Jonsbo U4 Plus use?

The case is designed around air cooling and has ventilation positions at the top and bottom for 120 mm fans. Cooler and graphics-card clearance still need to be checked against the exact parts selected.

Which motherboard sizes fit in the Jonsbo U4 Plus?

The supported sizes are Mini-ITX, Micro-ATX, and full ATX. That range makes the U4 Plus suitable for compact ATX builds, but the case is not the same class as a very small sandwich-style Mini-ITX case.
