I'm a fan of vintage audio so I definitely wanted to make a setup with old school binding posts.
I used some 70s akai amp leftovers that a friend of mine gave and a standard electrical case, I put the rpi 2 + amp on a cardboard/rubber base for more security (I think it was part of an Amazon ereader package!), a little cutting here and there, a 1.8a external power supply (hope it will suffice else i'll try to get a more powerful one, but still external), a TPLink wifi dongle and here we go!
Quick and dirty but quick happy! Seeing to change the current Yamaha speakers I'm using to a couple of B&W Solid. Volumio is running as OS at this moment.
