WTF I'M DOING HERE?

Do I get a fire if I leave them like this?
What I'm supposed to do to get a good wire management?

You're on the right track. Use an old power adapter to run an old case fan on the box. I did that for a router some years ago that got scary hot. Suspended it approximately in the middle of the box with some string and cut a hole for a 100 mm case fan one end and a hole about 120% bigger the other. Don't worry about a superpowerful gaymeme fan. Just get any air circulating in one side and out the other, best if intake is at the floor and exhaust is at the opposite top.

You can wrap the box in paper or cloth like a Christmas present to disguise it/ blend it or display your mad hardware h4XX0r skillz.

Cacat negrule, ce faci acolo?

Cable binders, proper length on your wires, a cable canal

There are actually cable canals which let you "loop" the wire multiple times so you have like 15 cm length but can put 30cm of cable in it.

Ikea has these storages for cables that help on the cable management, doubt it's gonna start a fire anyway

WHAT DO YOU THINK GUYS?
THIS OK?

coae nu

De ce? Acum căldura poate să iasă.

Add some fans.
Noctua preferred.

Cartonul o sa absoarba si reflecteze caldura, verifica-ti temperaturile

Pâi și ce-i de făcut în cazul ăsta? Găurile nu ajută chiar la nimic?

Passive cooling probably good enough for what you pictured in OP. The holes you cut for this pic are _probably_ "good enough." No promises, though ... I have no idea what devices you've plugged in & how hot they get.

Personally, since I have all sorts of extra fans, I'd add in one small, quiet fan just for peace of mind.

You don't seem to care how it looks, so that's up to you. You can paint the box if looks matter.

Probably make sure to place that power switch for the power strip where you can turn the whole strip off fast and easily. Use a sturdy enough box and you can stack things on and around it ... so long as you don't block too much air flow.

as recomanda sa faci gauri mici dar mai multe decat cateva mari, dar daca ai izola interiorul cartonului cu ceva (in afara de aluminiu lol) si ai face o deschidere pe sus ai avea temperaturi minunate

wtf i hate power plugs now

>The holes you cut for this pic are _probably_ "good enough."
At the very least it decreases the amount of fuel a fire get.

Ti ai făcut un calorifer din carton, bravo

...

Așa am făcut, șăfu'.

Wait, this is on the floor isn't it - MEANINGLESS NEATNESS - anyway put modems on the box they'll get kicked there.

A HOUSEFIRE. These power adapters need to be in a ventilated space. In a box like this they'll melt and start a fire.

buy a well ventilated computer case with some noctua fans and put them inside
