Description for: Lian Li Lancool III RGB Black – Airflow ATX PC Case
LANCOOL III RGB · BLACK · AIRFLOW CHASSIS
Give your workstation room to breathe.
An airflow-focused black PC case with mesh panels, hinged tempered-glass sides and four included 140mm PWM fans for a spacious workstation build.
Four 140mm fans · ATX / E-ATX · GPU support bracket
Where it fits
A practical chassis for a desktop AI or creative workstation with substantial cooling and cable-routing needs. The included fans provide an airflow starting point, while removable brackets and accessible panels simplify assembly and maintenance. Hardware and thermal demands still determine the final fan and radiator configuration.
Compatibility before checkout
Supports ATX, micro-ATX, Mini-ITX and E-ATX boards up to 280 mm wide. Check GPU length, connector clearance, PSU length, drive-cage position and radiator placement together: clearance figures are not guarantees for every combined configuration. For a conservative air-cooler selection, keep within the 185 mm clearance stated in Lian Li’s cooling guidance.
Expansion and bandwidth explained
The chassis has eight expansion positions but does not provide PCIe lanes. Motherboard slot layout, GPU thickness and cooling clearance determine how many cards can be used. A vertical GPU kit is optional and not included; choose one explicitly compatible with the case.

Frequently asked questions
Does it come with a power supply?
No. Select a PSU appropriate for the complete workstation and confirm dimensions and cable clearance.
Are all four included fans RGB?
No. The RGB version has three front ARGB fans and a rear PWM exhaust fan.
Can I install a 420 mm top radiator?
Lian Li supports this with specific installation restrictions, including RAM height and rear-fan clearance. Check the manual before selecting the radiator.
Does the case make a four-GPU system possible?
Not by itself. Electrical lanes, motherboard spacing, card thickness, power and airflow must all be compatible.
