Mounting WLAN router, switch, 2 Raspberry Pis and a power strip

Question

Hardware I would like to mount

• Router: AVM FRITZ!Box 7590
• Switch: Netgear GS116E-200PES 16-Port
• 2 * Raspberry Pis (3 & 4)
• various CAT.7 cables
• Powerstrip
• ??? (ideas are welcome, should be related to router)

The switch may be a bit oversized. It comes from my old apartment where I had a LAN port in every corner in every room. I still would like to continue use it in case I'm moving to a new apartment where it can be put to good use.

I want to mount it on a wood board and place the board on a wall. That wood board can be put and removed from the wall (so no permanent install) in case I'm moving to a new apartment I can just take the wood board with me instead of rewiring everything again.

My questions:

• How thick should the wood be?
• What kind of screws should I buy? (How big and how deep?)
• For the wall mounting:
  • How do I create the "hooks" so I can mount it on the wall and remove it from the wall? Like when you are hanging up pictures. Which "hooks" should I get?
• Cable management:
  • What do I buy for cable management?
• What do I need to pay attention to?
  • Risk of fire due to hardware's close proximity to wood?
  • Bad idea, because ... ? Do this instead?
  • ...

I've seen a nice DIY article about such project before but I lost the article. Answers with links to those articles are also welcome.
I'm a novice at home improvement and would like to start with something small like this.

Answer 1

1/2" plywood would be fine. If the hardware has keyhole mounting holes, I'd get 1/2" pan head screws for that. Get whatever size would fit the keyhole. Disclaimer: YMMV, IMHO there's no fire risk, despite all the hardware, there's very little power actually being drawn, so I wouldn't worry about that.

Command (brand) hooks are usually the go-to for attaching things to walls without damaging the surface, but you are probably above the limit for what they can hold. A small picture hook would probably do, although would leave a small hole.
