The interior of any enclosure is only as good as the material it's made out of, and the interior of the DH-104 is very well made, offering smooth edges and no sharp surfaces of any kind. The motherboard tray is not removable, but there enough room inside the enclosure to move around a little bit, when you need to install a motherboard. The layout of the interior was well thought out, and offers no relevant bad points.
You can easily remove the hard drive bay for installation of your hard drives, and the bay uses ruber grommets to keep vibrations to a minimum. There are two fans already installed into the enclosure for proper air flow, there is one 120 mm fan x 1, 1300 rpm in the front for air intake, and one 120 mm fan x 2, 1300 rpm in the back for air exhaust. Everything on the interior of the DH-104 is high quality and easy on he hands. Even someone with big hands should have no problem working within the confines of the DH-104 due to its ample room.
