I removed my 12v supply and simplified everything to run off the 24V supply. Just need to pair up 12V devices in groups of 2 in series . E.g. 2 fans or fan and motor
Less things to go wrong and less space required in the box

Also I'd add a switch to the water cooled spindle pump - looks like it will run all the time which will be annoying plus may heat the water a little
