Case for active PoE Splitter (active to passive PoE converter)

I've made this case for a active PoE splitter I bought from Ebay for about 3€. The original case was black and I wanted a white one. Also the original had a circular power plug which I didn't need because I use this device for converting an active PoE to a passive version, which simply converts the 48V to 12V and puts it out on pins 4&5 and 7&8 of the RJ45 plug. Therefore I desoldered the original plugs and soldered a new plug on the circuit board.
