The MasterCase H100 ARGB mini-ITX case joins the H Series as the smallest model available, complete with the series’ 200mm ARGB fan. Being the deceptive, tiny case that it naturally is, there’s room for a full ATX power supply and a low-profile graphics card to be hidden inside. 
Component versatility allows the H100 to be built as a portable gaming rig, a home theater PC, and a desktop space-saver with the potential to house a substantial amount of storage and powerful hardware. Combined with Cooler Master’s Fine Mesh technology and an integrated handle for portability, the MasterCase H100 ARGB preserves the robust feature set of the H Series while keeping its dimensions minimized.
