The C-303 Mirror impresses with its slightly mirrored Tempered Glass front panel, behind which three optional 120mm fans can be put in the limelight. The tempered glass side panel extends over three quarters of the case and offers a view of the inner workings of the case and the installed hardware. The spacious interior offers installation space for additional 120mm or 140mm fans, a choice of 120mm, 240mm or 280mm AiO water cooling and installation options for 2.5" SSDs. The 3.5" hard disks are mounted in a separate cage, which is located in the separated mains partition tunnel. In the lid of the case as well as underneath the power supply unit there are removable dust filters, which protect the interior of the case from annoying dust and are easy to clean. The overall package of the C-303 Mirror is rounded off by the side openings next to the mainboard tray, through which the cables can be laid behind the mainboard tray.
