And the inside:
Made with a scrap from my DIY audio rack for the body, mainly with a router, a Raspberry Pi 4B 4Gb, un HiFiBerry DAC2 HD and an MSL Digital Remote Pi (the three connected with a dual PCI ribbon that MSL Digital can create to your quotes) board that manages power on-off, soft start, and that is integrated with MoOde to shut down properly linux before shutting completely the power, and reacts too at MoOde.local shutdown command. It also offers On-Off from a remote (I learned this from my amp remote, to have both turned on and off together), and can with a bit of LIRC work, receive remote commands now from my CD player remote to Mac play/pause/stop/cdprev/next and so on.
The two fans harness is shown in the picture but is a bit noisy, so I removed it. Rpi is working at around 59°C, which seems fine to me, CPU still not throttled, load minimal (4%) while streaming from Spotify (moodeutl -m told me these).
I replaced the pushbutton and leds that came with the remote pi by my own (I do not like the usual pushbutton one can see on practically all the DIY projects, nor the too common red/green dual led), and went for more discreet pushbutton (the white knob at the back) and more fancy color leds (Orange for standby/off, blue for on, white for setup/firmware/shutdown sequence).
I deported the RCA output at the back, with WBT 0201 I happen to have; the Remote pi is plugged into a Cliff passthrough USB-C connector (Neutrik-like footprint), just to deport the mechanical stress of plugging/unplugging directly on the pcb.
The box is so an open base one. It has to openings on the sides, to take air. Now as I test without the fans in place, I hope they still do a kind of venting function... We'll see.

I love these DIY projects, I wish I had the oportunity to do this myself, I don't have the space for anything other than a basic tool kit & a cordless drill.
Nice job.
