Graham,
I'll be following your build closely as I have a similarly massive case plus a Canterbury traffo left over from an abandoned duo-mono HackerNAP build. The NCC300 is a good fit to those fins. How are you planning to manage the weight? The bottom plate isn't that strong, and it's a beast to move that thing on and off a rack. I was thinking of mounting it on inline skate casters and just wheeling it around.

Flash,
The weight is/can be a problem but once landed I don't tend to move them. I built a pair of monster Nelson Pass class A monos last year. With the case caps and two transformers was a two man lift really but I managed to site them on the floor adjacent to the speakers. The heat generated was to much during the summer, they worked/sounded OK but after a hour or so we were sweltering.
The floor plate to the chassis of the deluxe case is OK theres a double skin and will easily take the weight the transformers and pair of cap6s. The NP amps used two 625va TXs which came in at 10kG each. I'll also be using Les's new transformers which are somewhat lighter, as will be the cap6's compared to the 80,000uF per rail used in the NP.
The timely advent of the NCC220 voyager beat the NP amps by some margin so was an easy decision to build the 220s into one of these cases and glad I did. And now onto the 300s..I still have another 5U deluxe case which still has a 50watt NP Class A within. I'll strip and use this for a second dual mono 300 at a later date.
Ive just got to be mindful that at a later date (quite soon I think) after this build I'll be wanting to separate the front end with its own PSU so will have to leave room for two additional TXs and caps.
