I've used a 150mm x 105mm x 55mm aluminium project box (~AU$15) to house these. With the Pi mounted front and left, the volume knob is on the centre line, and the space to the right of the Pi allows a stereo plug to connect to the headphone jack on the X400 (I run that to a 3.5mm socket on the front). There's room at the back to allow a DC jack to run to a switch and socket, and to mount speaker terminals, as well as a panel mount USB socket to break out the Pi's USB. I have toggle switches connected to the jumpers to allow the speaker and headphone amps to be switched on/off and to engage the mute function. In all, another ~AU$15 in jacks/terminals.
I've models (https://www.thingiverse.com/thing:2539748) for the front and rear panels, and a mounting plate for the Pi to suit a box such as here (http://www.aliexpress.com/item/Aluminum-Box-Enclosure-Case-desktop-DIY-55mm-2-16-H-X105mm-4-14-W-X150mm-5/32342220019.html - no affiliation, it's just what I've used).
If there's anything else I can show, please let me know.
