Think Big. Build Small. O11D MINI adds to the O11 Dynamic series, the classic and mordrn looking case range. A case that can accommodate the maximum number of water-cooling configurations without being oversized. With a modular back panel design, you have the option to choose from 3 slots, 5 slots, or a 7 slot I/O shield to optimise the case to the configuration of your choice. Supports mini-ITX, micro-ATX, ATX, and E-ATX motherboard sizes and up to 9 fans to cool the chassis. YOUR CHOICE OF MODULAR BACK PANEL Decide how many expansion slots you need. Calculate the size of your fans & accessories. Pick your motherboard type. 3 kinds of back panels to meet your demand! SIDE RADIATOR CONFIGURATION WITH LONG GPU The 30mm space behind the side fan / radiator bracket allows users to mount fans, thus efficiently intake fresh air to directly cool the radiator and leaves enough space to install long GPUs in this compact case. WITH WATER COOLING IN MIND - MODULAR PUMP STAND Friendly to custom water cooling users, the three different pump stands included can accommodate different scenarios. EXQUISITE APPEARANCE With a blend of brushed aluminium and tempered glass, the O11D Mini not only looks classic and modern, but also has a high-quality feel and touch on the exterior. DUAL-CHAMBER DESIGN FOR CABLE MANAGEMENT Carried from the design of the O11D series, cables quickly pass to the second chamber through rubber grommets. Multiple tie points and Velcro strap channels are provided to tidy up the cables while the SSD mounting bar helps keep the loose cables all snuggled up to ensure a clean look and prevent the right-side panel from not closing or bulging. COMPLETE DUST PROTECTION All 3 ventilation intake sides are equipped with magnetic dust filters and a removable dust tray to prevent the dust from entering the case.
