While the Gigabyte C1007UN-D mini-ITX motherboard is made for low-end PCs, the IF 400 case most definitely is not.
Indeed, the IF 400 does not only use the ATX mid-tower form factor, it even has an all-black paint coating and all the things necessary in a gaming enclosure.
Sure, it doesn't have many embellishments, but it does get two 5.25-inch drive bays, five 3.5-inch / 2.5-inch drive bays, and a 120 mm fan at the back, plus one on the front.
Both 5.25-inch optical disk drive bays have tool-free retention modules. For that matter, two of the 3.5-inch compartments are tool-free too.
Gigabyte's IF 400 is made of 0.6 mm-thick SGCC steel and ABS plastic. It measures 185 x 412 x 450 mm / 7.28 x 16.22 x 17.71 inches. No price known yet.
