Smallest itx compact build

[Evilgenius]

Hello everyone,
I was brainstorming ideas and came up with a idea to build the most efficent and compact itx gaming pc with freesync.
The components:

Intel i5 8400
Corsair vengeance lpx ddr4
HDPLEX Hi-Fi 400W DC
Asrock Z370M-ITX/ac
Amd rx vega 56 nano
Samsung 970 evo m.2 ssd

This concept will require a custom heatsink that will be shared among the cpu and gpu, hence why i had the amd vega 56 nano in mind.

I was going to do this by stripping the fans/h3atsink from the gpu and install it via a riser cable with the gpu facing the cpu die. Inbetween the two dies, i was figuring if its possible to build a custom heatsink that can cool both processors efficently with micro fans attached on the side.
So basically the gpu i/o will be on the left, while the mb i/o will be on the back. For the casing that will be built once i have the dimensions.
I will need your input guys, i have no idea how to build a heatsink.

Do you already know this "case"?

As a starting point, check out the work of this mad man. There's some good info in the posts before and after as well.

THANKS!!! That was exactly what i was gonna do with my build
i believe its possible to be able to reduce the size , w micro fans and some rework around the heatsink,
and also attaching a pcie 16 connector so the nano's ports will take little space above the motherboards ports.
what do you think ?

I'm tagging @duniek in case you have any doubt (he might be able to help you) as he is the one who has created what he calls as "PurePC".

Good luck!

I'm sorry for any inconvenience.
