Volume is the outer bounding box (W × H × D), which is usually a bit more than the volume the manufacturer quotes.
Cube case buyer’s guide
Cube cases are wider and shorter than towers, often with a dual-chamber layout: the motherboard on one side and the PSU and drives on the other. They range from compact ITX cubes around 20 L to Micro-ATX and ATX cubes of 40–60 L.
Who should buy one
- Home server and NAS builders. Cases like the Node 804 hold 8–10 3.5″ drives.
- Showcase builds. Dual-chamber cubes such as the 2500D Airflow hide cables and show off components.
- Low shelves where height is limited but width and depth are not.
What to check
- Footprint. Cubes are often 30–44 cm wide and 39–47 cm deep, so they use more desk area than a tower of the same volume.
- Motherboard orientation. Horizontal trays (Core V21, HAF XB) put the GPU flat and change airflow paths.
- Drive-cage vs. GPU clearance. Storage-heavy layouts can limit GPU length.
Desk placement tips
Check the top view in the desk tool. A cube beside a monitor can take up much of a 60 cm deep desk. Cubes work well under a monitor shelf or on a low sideboard.
FAQ
Are cube cases good for airflow?
Often yes. The short air path from front to back and separate PSU chamber help. Horizontal-board cubes cool the GPU differently, so check reviews for your layout.
Can I stack something on top of a cube?
Some, like the Thermaltake Core V21, are designed to stack. Otherwise keep the top clear if it has fan or radiator mounts.
