Assuming the dimensions on the spec page are correct and my maths are correct this case is around 22 inches wide, far too wide to get into a 19" rack, especially accounting for some kind of adaptor to get it in there.
For 300$, this might be a better value for my build than nfc S4 mini considering 200 (case) + 22 (power button) + 35 (riser cable) = 257. If S4's mobility isn't a must have.
