I saw somebody selling a briefcase eurorack case on some auction plattform. Realizing I could do myself, I went trifting for a cheap briefcase. 

Some tipps here

• Take some rails with you. If possible mount some 3U or 1U modules or blinds. 
• Keep in mind to have some depth for the modules *. As well as some space for knobs.

* I for example would recommend the Super Disting EX in a rather small build. Because it gives you a lot of possibilities in only 8HP.  But it has a depth of 50 mm.

I went for 2x3U.

I screwed a piece of roofing battens into the case and the bottom rail directly onto them. 

The middle rails are just screwed together and are laid onto some standoff I laser cutted out of some scrap wood.

The top rail I screwed onto some pieces of roofing battens as well.

The rails are held together by the modules in the case.

Next thing was the PSU.

Since I had a spare NiftyCase laying around, and they have a PSU / MIDI In and Audio Out already in the case, I decided to just canibalize this.

The NiftyCase electronics consists of two PCBs, connected with a ribon cable. I laser cutted a panel out of some MDF used from the back of a broken image frame (from back in the days when the swedish furniture store had frames with back that wasn't cardboard). 

Later I realized, that the Audio out is only mono. So I drilled some holes to mount a 1U Intelijel Headephones out.

The PSU / MIDI / Audio unit is just screwed onto the pieces of roofing battens the top rail is screwed onto, and rests on some laser cutted plywood at the far side of the brief case.
