Product information

Description

Darkflash DK351 computer case is a mid-tower ATX chassis in black with tempered glass side panel and four CL6 fans included.

It supports a variety of cooling options — up to four 140mm or six 120mm fans, and space for front radiators — while offering tool-accessible panels for easier maintenance and component installation. Four CL6 fans are included in the box.
