Lian-Li EX-H34 HDD rack supports 4x 3.5" HDD's in an all aluminum frame and housing. The HDD rack has a front loading door, with individual handles on a bracket for each HDD, as well as a back panel PCB designed to accept most modern SATA HDD configurations in a Hot Swap Plug & Play configuration supporting RAID 0, 1 and 0+1, depending on your motherboard configuration. The Lian-Li EX-H34 HDD rack takes up the equivalent of 3x 5.25 bays, and can be installed into the front 5.25" panels of most modern chassis. This is ideal for those cases with rows of 5.25" bays, but with very little HDD space. To keep the device cool there is a 120mm fan (1500RPM) with a washable nylon filter keeping dust and debris out. The lockable cage complements Lian Li style with the hair-line brushed anodized aluminum in a black finish, combined with finely filed edges, and hand crafted tooling to prevent jagged edges, lending both safety and elegance to this neat HDD cluster rack.
