E-ATX is one of the largest and rarest motherboard form factors, which means that cases big enough to accommodate them are equally large and rare. Thermaltake has just launched one.
Called Core V71 (it sounds like a CPU really), it is fully modular (customizable 5.25 / 3.5-inch drive bay cages) and has tool-free installation for ODDs/HDDs/SSDs.
It also has three 200 mm LED fans and a 140 mm fan, plus room for a fourth 200 mm fan and three 120 mm ones.
Water cooling is supported too though, and might be preferred (360/420 mm front/top radiators, 120 mm rear, 120/240 mm bottom).
Sadly, Thermaltake did not say what price the Core V71 case sported. It did post a product page though.
