Chieftec UNI Series BS-20B-OP Mini-Tower Case, Black

The Chieftec UNI Series BS-20B-OP is a mini-tower case engineered for space-efficient system builds using Micro-ATX or Mini-ITX motherboards. Its compact chassis is well-suited for home or office environments where a minimal footprint is a primary consideration. Constructed from SGCC steel, the case accommodates standard ATX power supplies and provides clearance for graphics cards up to 270 mm in length. The internal layout is structured to house a functional set of components within its approximately 20-liter volume, balancing size with hardware compatibility.
