Compact Green Aluminium Chassis

The Velztorm O11D Mini is a Micro ATX mini tower finished in green with aluminium and tempered glass panels. It accepts Mini-ITX, Micro-ATX and ATX motherboards while keeping a small footprint. Three magnetic dust filters and a removable tray protect the interior from dust.

Three Horizontal Expansion Slots

The rear panel provides exactly three horizontal expansion slots for add-in cards. Builders who need more slots for multi-GPU arrays or extra capture cards cannot use this chassis. Vertical GPU mounting is not supported by the supplied back panel.

Dual-Chamber Airflow Under Load

A dual-chamber layout routes cables behind the motherboard tray through rubber grommets and Velcro channels, leaving the main chamber clear for intake. The 30 mm gap behind the side bracket lets 120 mm or 140 mm fans feed a 240 mm, 280 mm or 360 mm radiator without crowding a long graphics card. Top, side and bottom mounts each support three 120 mm or two 140 mm fans for sustained thermal performance.

Questions about this item

What does the 360 mm top radiator limit mean once the case is built?

A 360 mm radiator can be mounted in the roof, but only if the motherboard and CPU cooler clearance allow the full 360 mm length without fouling RAM or VRM heatsinks.

Which USB standard does the front Type-C port use and what speed does it cap at?

The front panel includes one USB 3.1 Type-C port operating at the 3.1 generation 1 rate of 5 Gbps.

How much clearance sits behind the side fan bracket for a radiator and GPU?

The side bracket provides 30 mm of space behind it, letting you mount a radiator and fans while still fitting a long graphics card.
