Mid-tower case for ATX builds
The be quiet! Pure Base 501 LX is a mid-tower chassis that accepts ATX, Micro ATX and Mini ITX motherboards. Seven expansion slots and a tempered glass side panel suit gaming or workstation builds. Two 3.5 inch and five 2.5 inch internal bays provide room for mixed storage.
Thermals noise and power
Four pre-installed 120 mm fans give immediate airflow through front and rear positions. Additional mounts allow two 140 mm fans at the front, one 140 mm at the rear and two 140 mm at the top. Radiator support reaches 360 mm at the front, 240 mm at the top and 140 mm at the rear for liquid cooling.
Build quality and connectivity
ABS and steel construction with a tempered glass window creates a rigid, quiet enclosure. The 368 mm GPU clearance and 178 mm CPU cooler height accommodate most modern components. A 200 mm power supply limit means longer units will not fit.

How do I install the pre-installed 120mm fans and which step do builders often miss?
The case ships with three 120mm fans at the front and one at the rear. The step often missed is checking each fan’s arrow for airflow direction so all four push air in the same path.
What maintenance will the drive bays and dust filters need over time?
Two 3.5-inch and five 2.5-inch bays use tool-less trays; remove trays periodically to vacuum dust. Front and top magnetic filters slide out for cleaning without tools.
What is the first cooling limit reached when running a 360mm front radiator under sustained load?
A 360mm front radiator fits, but the 178mm CPU cooler height limit and front panel clearance restrict pump-block thickness, so combined radiator-and-fan depth becomes the limiting factor.
