Because I love building boxes that hold other boxes!
Plan is to build a Heater Box to hold 4 Canaan Nano 3S's while producing airflow to help keep the unit cooler and also keep the PSU bricks cooler.
So here we go! Hope you like it.
Test print for initial fitting and to determine where I want all the cables to route and how I want to prepare airflow.

I Love it! I plan on picking up a couple of the nanos as I can and this box would be perfect. What is the power supply for the fans? I have some old 140mm corsair fans (4 pin connector)

Also, are they pushing or pulling airflow?

PSU, no idea yet, going to look at a fan splitter for pcs that can power using a normal outlet plug.
Will test push and pull, I wanted push first to help cool the power bricks better as those get hot AF to try to limit the burn out.

Vent out the top with a Bitcoin (B) or some other bad ass logo or design as a heat release?

Maybe, Want the air to all flow in one direction to maximize cooling. The testing will be fun

V2 of the 4xNano Box.
I really wanted to allow this thing to also cool those power bricks they GET HOT. So opened up the top to let heat out while also having the 140s on the back blow cool air over them.
Added wire management for zip ties to get a little cable management, added slots in the brick tray to route power cables for the nanos through.
I like the look of this.
Will experiment with push and pull when I get the designed wrapped up.
Test print time.
