Looking good!

I started using "marking strips" under my terminal blocks. Extra level of insulation and numbered locations. Not expensive. Example (click).

Well now... between all the different ways of doing things, I like the way the amps have the power wires coming in from the back of the board and running along the inside of the chassis as is shown in the diyaudio-f5-build-guide pdf.

Unfortunately I wasn't paying attention to the longer standoffs used in this guide and this method does not leave enough room with the smaller brass standoffs that come with the premium parts kit. (Forgive the use of the odd-ball colors as that was all I could find locally in a reasonable gauge). Fortunately the parts kit comes with a plethora of these little standoffs so I doubled them up. I commented earlier about how installing the MOSFETs looked like it was going to be a pain, and quite simply, I could see no realistic way of doing it without taking the sides off (also somewhat of a pain at this stage). I was also a little worried that with the standoffs doubled up like this that the leads on the MOSFETs might not be long enough.

Just barely!
And that's enough for me for now. We're jamming tonight!!

move tiny NTCs to touch ceramic part of output mosfets , not bare big washer

not one F5 goes BoomBigBadaBoom , just because paint insulation on NTC was lousy ..... not having anything with their resistive quality

besides that , Moi again - rise that mains NTC from base plate .....

Good idea. Just bend it away from the chassis floor a few more MM.

Hah! I misinterpreted your reference to NTC as something I was doing was Not To Code. Probably correct either way. You're talking about the CL-60s. NP! I'll put them over top of the connections. As for the ones on the Mosfet, I saw a pic somewhere of exactly this so I thought it was fine. Truth be told, I don't know why they are there anyways. Please explain. I thought they were some kind of safety devide if the mosfet over heated and therefore the washer would make little difference.
