I'm interested!  I like the idea of using an ammo can as a case.  Any updates?

Any further updates?

MAJOR UPDATE!
There is still plenty of work to do, but so far I am pleased that there have been no mess ups... besides the fact the PC is a bit heavy. 
 
I can run prime95 and the AMD 3960x wont ever go over 66C! CPU idle is as low as 35C...
 
I am going to add the lid on top with a 3D printed hinge, and include a 3rd radiator on that. 
 
This case looks like a mess... I only slapped it together to test. I can say however... 
 
Key things to note:
1. The upper left white box is a surge protector / power cleaner, this is built into the PC and will provide power to the "ammo belt" as well as the main PC PSU. 
2. To turn the computer on there is an epic red switch I wired into the motherboard.
 

I love everything about this build, the attention to detail is incredible. Would never have thought to incorporate the cables into the design the way you did. Amazing!

I am getting close to having the body of the case done, there is still a lot more holes to drill into the case to give a place to mount screws for the 3D printed parts. But in the next few days all of the metal parts should be completely milled and mounted! All that would be left is basic 3D parts. I also figured out how to mount and lock the ammo belt into the body of the case, thus relief pressure from the wires...
 
I want this done by at worst end of September lol. Longest PC build I have ever done... but worth it! 
 
Thank you everyone for the encouragement. 

Thanks for the update

Sweet concept!
