I agree about pushing the power connection to the board edge. I did that and there's enough clearance not to need adding insulation.

Otherwise what I did was to wind the toroids first and do a dry assembly of everything in the LPF area to make sure that everything fitted.
Then solder everything more or less from the outside in, finishing with the toroids.

A few other thoughts:-

When fitting the connectors between the boards I fit the boards together with the connectors then solder a couple of pins on each connector while fitted together so they jig each other.

I squeezed the pins for the PSU boards together slightly so they touched the board.

When soldering the BNC fit the display and main boards together in the top of the case with the BNC attached to the end plate and the plate fitted to the top half of the case. Maybe the other end plate also fitted.? This holds the BNC and main board in the correct orientation while you solder it.

Hans, I can add one tips:
When installing the input power connector, push it towards the board edge.
This will increase the very small clearance to the left encoder on the control board.
Nevertheless I put kapton tape on the encoder body facing the power connector
