Looks like some nice work and progress so far!I made some progress around South Africa's Rugby World Cup Victory and the associated celebrations.
Done some layout of components in the Electronics Box (EB)
Had a few discussions with @Michael Lane about the different Power Options on the Hat Board. My question was how to run more than 8 Relays. The solution we came up with was to run 8 x 5V Relays off the "Power 1" pins that are essentially just GPIO breakouts, and to use the "Power 2" pins through ULN2803 but to supply the ULN with 5V instead of the suggested 12V. This would allow me to run the 5V relays I have until I manage to source 12V relays or decide on another route.
I built a housing for some of the equipment wall warts
Biggest thing was doing a fresh install on the Pi. I installed Raspbian Buster with Desktop , but without all the bloat software. Installed Reef-Pi 3.0 and got it all running in Console mode on my touchscreen. Maybe doesn't sound like much, but I'm very pleased with progress.
If you have the 5 volt relay boards already just use them until they wear out. I have a @Michael Lane hat and am using it exactly as you are and havent had a problem with the 5v relay boards except for one relay that had a cold soldered joint and I even scored a nice set of 16 phoenix contact mini relays on ebay. Im too lazy to redo my build because my build just works!
