Default Another F5 Build

Maybe 6-7 years ago I started to catch the bug. I bought my first decent amp, a Virtue Sensation M-901 with all the trimmings, and a GR Research N3 - an MTM transmission line kit. Building the N3 led to another hobby in wood working but also got me thinking I'd like to build an amp. Tube amps were always something that interested me so I got a hold of Viktor Kung at VK Music to ask about them.
I've since built (2) Elekit tube amp kits, the TU 879S with KT88s, and the 8300R, but in doing so discovered I needed some more efficient speakers which led me to getting the 97db co-axial OB GR Research Super Vs (which I still haven't "properly finished but they are singing anyways!).
Early last year I started down the Class D path and ordered a bunch of Hypex modules and a chassis when I ran across an article on the Amp Camp Amp. For whatever reason - maybe the price along with some of the reviews - I ordered and built that and was quite frankly blown away. To that point my beloved Virtue amp was always my go to piece when I just wanted to sit back and listen to music. There is something just so full about that little ACA that brings life to music. This got me looking at some of the other First Watt kits and, after reading many reviews, in June of 2018 I started ordering parts for the F5.
One thing after another delayed it all coming together, but as of today, the last piece showed up - a package of Keratherm insulators I had simply forgot to add to the list. Up to this point I've been posting in several different threads seeking help and getting to the stage I'm at now. I'd like to thank 6L6 for his invaluable contributions through his PSU and F5 build guides. I've also had many people enlighten me thus far including rayma who's been great. I'll post a bunch of pics here. I had more from earlier on but between moving them from DropBox to different files I've managed to lose a bunch unfortunately, but I believe everyone here has probably seen the "un-boxing" of the deluxe chassis from Italy by now.
Pics of the progress below.

Tidied up some things - finished mounting the PSU to the stand-offs properly, added a few more riser tie-downs for the mains and put some tape under the terminal block per ZM, and mounted the amps to get some wire lengths.

For some reason I thought the Keratherm had a sticky side?
And actually now that I'm about to do it, installing the MOSFETs seems like it might be a bit tricky to get everything to line up properly....
