PC case Lian Li Lancool 207 Midi Tower Black

The Lian Li LANCOOL 207 is a compact M-ATX (Midi Tower) PC case that reimagines the traditional ATX layout to maximize component compatibility and cooling in a 45.5 L chassis. It supports ATX, Micro-ATX and Mini-ITX motherboards (max ATX width 244 mm), GPUs up to 375 mm, an ATX power supply, and a top-mounted 360 mm radiator thanks to an offset motherboard tray and a space-efficient internal layout. The case is available in black and white and features tempered glass side paneling, fully ventilated mesh on the front, top and bottom, and pre-installed high-performance fans for strong out-of-box thermal performance.

Advantages

The LANCOOL 207 combines broad hardware compatibility with an innovative internal arrangement: an offset motherboard tray increases clearance for top radiators while creating room for bottom fans directly beneath the GPU. A front-mounted PSU with side-facing connector ports simplifies cable routing, and the case includes multiple cable-management features—EPS routing, Velcro straps, a 24-pin grommet and dedicated drive space. Comprehensive mesh panels and four pre-installed fans provide strong cooling performance; independent lab testing awarded the case a Level‑S Chassis Performance rating for thermal management.

Suitable for

• Compact gaming or workstation builds requiring ATX/M-ATX/ITX compatibility
• Custom water-cooling with a 360 mm top radiator (push-pull possible)
• Systems needing strong out-of-box airflow and organized cable management

How to use

Install the chosen motherboard (ATX/M-ATX/ITX) onto the offset tray, then mount the power supply at the front with the connector ports facing outward for easy access; an extension cable is included if rear power routing is needed. Fit the GPU (vertical GPU kit available as an optional accessory) and connect power cables through the provided grommet and Velcro straps. For liquid cooling, install a 360 mm radiator on the top using the improved clearance provided by the offset tray. Use the tempered glass side panel to monitor components and access internal connections when needed.

Recommendations

For optimal airflow and cooling, maintain unobstructed intake and exhaust paths by using the included pre-installed fans and keeping mesh panels clear of dust. Consider the optional vertical GPU kit for display orientation and the front dust filter accessory for improved dust protection.
