“Supports a 280mm radiator” doesn’t always mean top-mount — some cases only fit a 280mm AIO in the front, some only support it at the top, and a few (like the Corsair 5000D Airflow) support it in three different locations. Where you can actually mount it matters for airflow direction and cable routing, so the location is called out for each case below.

The picks, in detail
Lian Li O11 Dynamic
The case that popularized the dual-chamber, showcase-build layout, with confirmed 280mm radiator support at the top.
- 280mm radiator support (top)
- Dual-chamber layout
- Panoramic tempered glass
- Excellent cable-management separation thanks to the dual-chamber design
- Larger footprint than a standard mid-tower
Lian Li O11 Dynamic EVO
The updated O11 Dynamic with a redesigned top mount rated for 3x140mm fans and up to a 360mm/280mm radiator with 83.5mm of clearance.
- 280mm/360mm radiator support (top)
- 3x120mm/3x140mm fan mounts
- Tool-less panel removal
- More top clearance than the original O11 Dynamic for thicker radiators and fans
- Priced above the original O11 Dynamic for the improved mounting
Fractal Design Meshify 2
A high-airflow mesh-front case that fits a 280mm radiator in the base/bottom position, alongside 360mm front and 420mm top support for larger loops.
- 280mm radiator support (base)
- 360mm front / 420mm top radiator support
- Angular mesh front panel
- Most flexible radiator mounting of the cases here — front, top, and base positions all supported for different rad sizes
- 280mm specifically only fits the base position, not front or top
Corsair 5000D Airflow
A dual-chamber airflow case supporting 280mm radiators in three separate locations — front, top, and side.
- 280mm radiator support (front, top, side)
- Dual-chamber layout
- High-airflow front mesh
- The most mounting-location flexibility of any case on this list for a 280mm radiator specifically
- Top clearance can be tight when combining a top radiator with tall RAM or a large CPU cooler shroud — check clearance specs against your other parts
Phanteks P400A
A budget-friendly airflow case with confirmed 280mm radiator support in the front — but no radiator mounting at the top at all.
- 280mm radiator support (front only)
- High-airflow mesh front
- 2x140mm fan front mount
- Lowest price of the cases here for genuine 280mm support
- Front-only radiator mounting — cannot run a second radiator or reposition it to the top like the other cases here
Cooler Master NR200P MAX
A Mini-ITX case that ships as a complete bundle with a 280mm AIO liquid cooler and an 850W SFX Gold PSU already included.
- 280mm AIO included in the box
- 850W SFX Gold PSU included
- Mini-ITX form factor
- No separate radiator purchase needed — the 280mm AIO and PSU are both bundled in
- Highest price on this list, though it includes two normally-separate purchases (radiator and PSU)
be quiet! Silent Base 802
A sound-dampened case with three pre-installed Silent Wings 4 140mm fans, supporting a 280mm radiator in the front position.
- 280mm radiator support (front)
- Sound-insulated side panels
- 3x Silent Wings 4 140mm fans included
- Quietest option on this list thanks to dedicated sound-dampening panels
- 280mm only fits the front — the top position on this case supports 360mm but not 280mm
Montech AIR 100 ARGB
A budget Micro-ATX case with confirmed 280mm radiator support at the front and four ARGB fans included.
- 280mm radiator support (front)
- 4 ARGB fans included
- 330mm GPU clearance
- Lowest price on this list while still fitting a real 280mm radiator, plus four fans included
- Micro-ATX only — smaller motherboard compatibility than the ATX cases on this list
Thermaltake S100 TG
A compact Micro-ATX case rated for up to a 280mm radiator at both the front and top positions despite its small footprint.
- 280mm radiator support (front and top)
- Micro-ATX form factor
- Tempered glass side panel
- Fits 280mm at both front and top despite being one of the smaller cases here — unusual flexibility for its size
- Micro-ATX size means less room for cable management and large GPUs than the full ATX cases on this list
Buying tips
- “280mm support” always means a specific mounting location, not the whole case — check whether it’s front, top, base, or side before assuming it fits your build’s fan/radiator plan.
- If your CPU cooler and top radiator will compete for clearance with tall RAM, check the case’s specific top-clearance spec (like the O11 Dynamic EVO’s 83.5mm) rather than assuming any “280mm-rated” case has room.
- Mini-ITX builders: the NR200P MAX sidesteps the whole radiator-shopping question by including one, which can work out cheaper than buying a case and radiator separately.
