The Jonsbo C6-ITX is the case to buy when you've already decided you don't need a flagship GPU and you want to keep the build under $400 total. The mesh-everywhere design and full-ATX PSU support are genuinely useful at this price point, and the carry handle is a nice touch even if it's not built for serious LAN use. The trade-off is the 255 mm GPU clearance — RTX 4060 Ti and similar mid-range cards fit fine, but most RTX 4080/4090 partner cards do not.
Full review
Budget Airflow
The Jonsbo C6-ITX is the value entry in this lineup, typically selling under $70. It's a steel mesh box measuring roughly 202 x 266 x 295 mm for about 16 liters of volume, with removable mesh panels on the front, top, and both sides. That all-mesh approach gives it airflow that punches well above its price, comparable to cases costing two or three times as much, and every panel comes off tool-free for easy access.
Jonsbo even includes a fabric carry handle for casual transport. It's a convenience touch rather than a serious LAN feature, and it's nowhere near as robust as the Hyte Revolt 3's aluminum handle, but it's a pleasant extra at this price. The materials and finish are clearly function-first, without the premium aluminum or wood touches of the higher-tier cases, which is exactly the bargain you're making here.
Compatibility Trade-offs
The C6-ITX's headline compatibility feature is power supply support: it's the only case in this round-up that accepts a full ATX PSU (up to 140 mm deep), in addition to SFX. For budget builders reusing an existing ATX unit, that alone can save real money. It also clears tall tower coolers up to 170 mm, the most generous CPU cooler height in this lineup, and supports both Mini-ITX and (tightly) Mini-DTX boards.
The catch is graphics. GPU clearance is capped at 255 mm, which fits mid-range cards like an RTX 4060 Ti comfortably but rules out most triple-fan flagship 4080 and 4090 partner cards. There's no dedicated radiator mounting either, though the chassis offers three 120 mm fan positions (top, rear, and bottom, with the bottom mount exclusive to the drive bay). This is an air-cooled, mid-range-GPU case by design.
Who It's For
The C6-ITX is the right call when you've already decided you don't need a flagship GPU and want to keep total build cost down, often under $400. The combination of mesh airflow, full ATX PSU support, and tall cooler clearance makes it a surprisingly capable budget host for a mid-range gaming or productivity build, and the carry handle is a bonus.
It's not the pick if you want premium build quality, a long high-end GPU, or liquid cooling; the NR200 and Terra outclass it on fit and finish, and the A4-H2O handles AIOs. But none of those match its price or its ATX PSU flexibility. For a cost-conscious first SFF build paired with a sensible mid-tier card, the C6-ITX delivers the essentials and skips the premium tax.
Strengths
- +Sub-$70 price — the cheapest legitimate option in this round-up
- +Mesh side, top, and front panels deliver airflow comparable to cases 2x the price
- +Built-in fabric carry handle for casual transport (not as robust as the Hyte Revolt 3's)
- +Supports ATX power supplies up to 140 mm — the only case in this lineup that takes full ATX PSUs
- +Fits 170 mm tower coolers — generous CPU cooler clearance for a case this small
Watch-outs
- −GPU clearance is capped at 255 mm — won't fit most triple-fan flagship cards
- −Less polished build quality than the Cooler Master NR200 or Fractal Design Terra
- −No premium materials — function-first design
- −Mini-DTX support is technically there but tight
How it compares
The budget pick in this round-up. Loses to every other case here on GPU clearance (255 mm vs 322-335 mm), but undercuts the Cooler Master NR200 on price while offering ATX PSU support and more mesh area. Vs the Hyte Revolt 3, the C6-ITX is the half-price alternative for builders who don't need a serious carry handle.
Who this is for
At a glance: budget-conscious builders running mid-range GPUs who prioritize airflow and want full ATX PSU compatibility.
