The split side window made of tempered glass on the Enthoo Pro provides a view of installed water coolers, LED fans, or simply RGB strips, all of which find ample space alongside robust hardware in the spacious interior. The stylish removable front made of plastic with a brushed aluminum look gives the case a sleek appearance with its beveled and offset sides. At the top, there are slots for up to three 5.25-inch optical drives or controllers for fans or RGB lighting, which can be installed without tools. Below, PHANTEKS has directly integrated a quiet 140mm fan for proper ventilation of the case.

Next to it are two HDD cages, each capable of tool-free installation of three 3.5-inch drives in a tray or alternatively, three 2.5-inch drives can be screwed in. Two additional 2.5-inch drives can be mounted externally on the support for the HDD cages. Two more 2.5-inch drives can be accommodated on optional brackets that can be installed on the back of the motherboard tray, which can support not only E-ATX but also SSI CEB boards from the server sector. Both HDD cages can also be removed to create space for oversized graphics cards, which can then measure up to 472 millimeters instead of the standard 347 millimeters. The PHANTEKS Enthoo Pro offers a total of eight expansion slots.
