The external part of Colossus M is made with black matte SofTouch material of good quality and workmanship, in the central part is inserted the Bitfenix logo and a large LED strip which also passes through the sidepanels . In order to maintain a clean and classic design, Bitfenix has equipped the front with a door with a magnetic closure. The top side is also made out of matte black SofTouch, and it features a big opening with a removable dust filter, which is useful for the assembly of the system and for the installation of additional fans. The
left sidepanel is absolutely smooth and without to any opening. On the right panel there is space for I/O connections such as power/reset buttons , two USB 3.0 ports and audio connections. Both side panels are secured to the PC case with two thumb-screws, something you are never tired of seeing. On the bottom panel we find four hard plastic feet with a shiny metal finish, which also lift the case up so that the PSU can get all the fresh air it needs. The adjustable legs make the case really stable, even committing no way to swing it. On the back of the case, there are 5 expansion slots for the graphics card.
