Well I picked up a 20x20x8 cabinet. My plan is to carry over this cabinet over from this build to a future build if I go that far. So I'm leaving space for a potential VFD.

For these two 34V PSU with fan, is there any considerations when installing them, orientation? Any lessons learned? Any general advice on cabinet layout?

Fans on the bottom pulling fresh air into the enclosure vent on the top just put filters in front of the fans and use a filter for the vent. Also you want more air coming in than exiting, the enclosure should become pressurized. You also want all the items that put out alot of heat mounted at the top. And keep ac power away from dc power and the electronics also keep the VFD away from the drivers and control board.
