I've been using this kit for around 7 years and it works great for computer teardowns with odd/small screws.
 
Edit: My kit is magnetic, but it looks like the newer version might not be? Edit: I forgot that I had added a stack of small neodymium magnets (like these) under the twisty part of the handle (you can just pull off the black bit and add a stack - it works extremely well).

I haven't seen the Dark screw but most M.2 screws I have seen have just been a philips and I have just used an eye glass screw driver I had to tighten them.

I'll give it a try. gonna mount another nvme soon, and change battery, btw what battery does this board take, since
its it flat
 

Sweet, I have those at work. So if the box is unplugged for awhile, and i get the cmos error in x299 UEFI screen, then
its the battery?

Have a question: Where do the M2 Thermal pads need to be placed?
Can't find instructions in the manual.
 
Thanks
