Yep those tact switches will fine.
I made the foam so that the DNA will cradle into it. Once I have all the wires soldered it will pretty much just be sandwhiched in that cavity in the foam and wont go anywhere. I will however put some varnish tape across the top of it. Not so much for adhesion, but for electrical insulation and abrasion resistance. The Lipo will be sitting over the top of it and I dont want any sharp edges of the DNA or the solder joints wearing a hole in the Lipo.
Not horizontally, but it would have fit vertically. I just prefer the horizontal orientation.
Yes, the board will be sandwiched in between the foam and the LiPo, plus the foam has a cutout for the board to sit into, so that the LiPo will sit level.
Got the 4200mAh 7.4 v shorty in for my Raptor weekender. Popped it open and it has 4 2100mAh cells. two paralleled packs then those 2 packs in series. The 4 cells measure 85x43x23, not bad for 4200mAh 7.4v or 8400mAh 3.7v.

You did a much cleaner job at splitting the case open than I did! Is that center connection for balancing?
I like the foam blocks that the A-Specs use to support the tabs. Havent tried to actually take tabs apart and reconfigure them yet. Whats the sweat factor on doing that?

I have been doing it a long time...
No sweat factor just common sense and caution. It brings a balancing harness.

I am trying to wrap my head around PTC fuses.
From what I gather the "Hold" is the minimum amount of guaranteed current allowed to pass, and the "Trip" is the maximum current allowed under any circumstance. The difference between the "Hold" and "Trip" is essentially a deadband and ambient temperature will determine where in that band it trips. The warmer the ambient environment the more it is derated, i.e. the closer to "Hold" it will trip. So, if the inside of your Mod starts getting warm, it actually reduces the point where the resistor will trip.
Am I getting this right?
If my understanding is correct, then placement of the resistor could be important. For example you wouldnt want it adjacent to a voltage regulator which gets warm, or a battery being pushed hard.
Anybody know what the failure rate is of a PTC fuse?
What about failure mode, i..e. can it fail in a "Closed" state?

Just got my shipment from Wallbuys.com that I placed on 12/29. It was packed well, just over 2 weeks to get here using their default free shipping, not bad. They are maybe a few percent higher than FT on most things, a lot higher on batteries, but I would use them again. Just another option, I bet that more options will pop up soon.
Got everything wired up except the battery, and that will be the easiest part of all of this:
Not sure what that line going across the screen is, something to do with the camera scan time because it doesnt have it when you look at it:
Now I just need to hook up the power supply stuff and apply the Girlie Flowers to the outside. Another night.......

Nope, sorry. I was just so damn happy to get it done that I totally ignored taking photos.
However, I saw a picture in another thread that is very similar to what I did:
