Check that out, an all naked full-fledged ATX case which can take advantage of the exponentially higher volume, to passively cool processors with TDP of up to 95W. Haxx.eu unveiled one such case, the Fanless Case 0.1. Made of 3.1 mm-thick aluminum sheets, the case can house common ATX, micro-ATX, and mini-ITX motherboards. It offers 7 expansion slots, two 5.25-inch drive bays, and five 3.5-inch bays that can each hold 2.5-inch drives.
When we talk about the difference with other cases, we see that this case has unusual cut outs. The top most panels pack a 140mm fan and a couple 120mm bottom intakes which wisely divide the load of the fan. A massive monolithic aluminum heat sink drifts over the CPU socket area which is connected to the CPU over a copper base and heat pipes. The heat sink can submissively cool CPUs with TDP of up to 95W.
Talking about its size, it measures 18 X 420 X 420mm with weight still not disclosed, but we expect it be somewhat on the higher side. Tie it with an inactive cooled PSU like Silverstone Nightjar, a passive-cooled graphics card and there you go. One of the disadvantages this case carries with itself is the price tag. It will cost you €333.
