cgcolormax2-b console
120v > 12 vdc > ATX psu board > 12vdc, 5vdc,3.3vdc > power distribution

Remaining to be done:
-Hinge the case cover
-IO Shield

Would be nice:
-Refinish the case
-Find a better way to connect the ps/2 kb

Nice Project!

Right behind the PS/2 connector is a 1x4 header that you could use.

Tres retro :)

These all-in-one case builds are great, but I think you'll eventually want to get the SD card slot routed to a convenient external location. I swap SD cards quite often, and popping the hood on the case every time would get annoying.

I've seen micro-SD extenders to do this; I imagine there are variants for full-size SD cards as well. But, it feels like a cheap & reliable "standard" way to access files on the SD card wirelessly is right around the corner, so this could become a moot point.

FYI, I screwed my CMM2 to a block of wood early on as a temporary mechanical solution, planning to do something like you did (with a gutted Apple //c case...) but I found the "naked" approach works well for just about everything, and now I even prefer the homebrew way it looks. Plus, I purchased a Raspberry Pi 400 around Christmas, which largely satisfied my desire for an all-in-one retro computer :)

Happy Maximiting !

Yes, that's the ticket :)

Somewhat related, I keep reading about people here having all sorts of mechanical and electrical heartache while soldering their DIY SD card connection. Possibly, hacking a ribbon cable like this could offer some relief.

I finally got the keyboard wired in, I messed up the ps2 holes so had to be creative on getting the kb connected but it works now!
