How to fix multiple units in a closet?

Question

Computer networks

I welcome everyone!
It is necessary to fix 1U router and 2U server in the closet. There will be wallpaper at the back, and wooden walls on the sides. So here's how I can cover it all up so that it's fireproof. Maybe something like foil. And how to organize cooling, because the cabinet will be closed all the time, but in fact there should be enough air due to holes between the walls.
Still have questions about the wires. They brought me a bunch of wires under the router, but I don’t know how to twist them and generally how to stick them into it and so that everything doesn’t hang out. Need advice too.
Thanks in advance!

Answer 1

Foil is an excellent conductor of heat - what kind of fire safety is this?
On the contrary, you need heat insulators, for example, something like a minerite:

Honestly, I don’t know how it affects the technique, but the dust from it is many times less than from GVL (even primed).
First, you “lay the wires beautifully” with bundles, then “stick them in”, then grab them with clamps (screeds) in place, grabbing some fasteners on the wall so that they do not sag.

Answer 2

To be honest, servers are not designed to work in wooden cabinets, and where servers are usually located, fire safety is achieved by other methods - installing alarms and fire extinguishing systems. In the cabinet, the temperature regime is not suitable for organizing stable operation of the server. Unless, of course, cooling is somehow brought into the cabinet. At my house, a 4U server lies on a hanger under the ceiling, it contains a regular desktop processor, but, despite more or less free air access, the temperature conditions there are still worse than in a normally organized rack.
