Befaco 7U Case: DIY Build



Letโ€™s slowly meander through the building of the new Befaco 7U Eurorack Case. You get to build the TrolleyBus power supply, the I/O board and then bring it all together into a fabulous case that can be mounted on a modular arm.

  1. My eyes lit up the moment I saw the LK Delay going in and then disappearing…… I then had a Homer Simpson moment backing into the bush haha. Must be so hard choosing when you have a fair bit of Eurorack.

  2. Why not superglue the "black boxes" into position along the edges of the PCB to hold them in place while you solder them? I don't like the way they are moving around as you solder them, seems like a recipe for dry joints.

  3. That VESA mount is gonna be so good for you being able to video with! Thanks for going through the pain of the first build for us. Seems odd they put the HP ruler on the back of that board though.

    Just got my first couple of 1u modules, so looking forward to seeing what yours are like. ๐Ÿ˜€

  4. I have everything mounted on VESA mounts in my studio, everything can be swung around and repositioned. My main music comp and tracking area area is a mobile hydraulic standing desk with VESA arms and mounted studio monitors and tethered to a long snake, so it sounds famous no matter where I drag it off to. Same deal with my stationary worktable, everything on VESA to allow for the largest workspace.

  5. Looks lovely, I'd buy one, as im looking to update my 4 ageing, but still fully operational, Doepfer G6 baseframes, but the price seems a little high.

    I'm sure it's of premium quality, but โ‚ฌ650 still seems a little steep, or is that the price for a fully built case, rather than the kit?

    – love to ALL, feel no hate

  6. This could not have come at a better time for me ๐Ÿ™‚ looking into 7u104 cases atm, but that arm thingy is just caf!
    Befaco have nailed a market space with this case.
    Great work thx!

  7. That VESA feature actually seems to be really neat! I could imagine pulling it to the center of my small desk whenever I'd use my rack and then shoving it off to the side if not in use, freeing up desk space in the process. If Befaco made an 84hp 7U version, that would make me seriously consider it… But I would need to find a strong monitor arm first ๐Ÿ˜€

  8. Those 2 hardware pieces that came unattached are supposed to be pressed permanently into the sheetmetal. The way you have them installed will not prevent the PCB from moving around and might eventually work the others loose. Depends on why those 2 failed. The factory might have just forgotten to press them. If they popped out after being pressed then the other ones might be susceptible as well. They are known as PEM fasteners if you are curious… In any case, you should have a non-conductive spacer between the PCB and the case to prevent them from touching. You might be alright because the edge connectors can act as spacers, but you should be careful and let Befaco know about it too…

  9. Tape and RTV are typically used to assist with assembling components that like to move (or worse might actually break off.) That along with 1-2 helping hands would have gone a long way to making some of this easier.
