One lucky case in the Mini-ITX market is the Apevia X-Fit-100 Mini-ITX Case. The X-Fit-100 offers a slim profile and sleek look that will work with any mini-ITX application. There is enough space to fit a 2.5" hard drive, slim optical drive, and a low profile PCI card. The X-Fit-100 comes equipped with a Apevia Flex ATX 250W power supply, which is more than enough for a mini-ITX system. There are vents on the top and sides that help expel heat and keep the case quiet. The X-Fit-100 also has a sturdy build, constructed from 0.7mm metal SECC. The style and finish is black, which matches perfect with most people's decor.
