Any recommendations on building your electronics enclosure yourself versus buying one? I am struggling to find one that I think will be large enough for any sensible price. I want to fit everything in the sam enclose, which includes:

(3 phase 400V mains)
- AC line reactor
- Mains filter
- E550 Sunfar VFD
- 4x Dyn4 drives
- 1A schaffner filters for each drive
- MB3 breakout board
- 1 or 2 24VDC power supplys
- Mains circuit breaker
- Contactor for E-stop circuit
- Relay for E-stop circuit
- Circuit breakers for each independent phase (insteaf of regular fuses)
- Terminals

It starts to seem like I would nees atleast a cabinet sized 800x600x250mm. I figure welding my out of sheet metal would be cheapest.

Don't buy anything until you have everything electrical and lay it out on the bench. Servo drives require a lot more space than steppers for cooling purposes and just physically larger anyway. Also think about fitting fans and the Air flow when placing drives etc.

Given that your mostly using extrusion then I'd use aluminium panels and some small extrusion and build the control box into the lower frame if possible.
