How does one actually prewire cables in the central location? (alien.top)

Two questions! End goal is to have a small rack in the closet with the cables hooking to the patch panel. There's a mix of fiber, RG6, and CAT6. Service is RG6 for 1200/45 (included for completion).

For starters, I've got almost all my runs done (not all are in the second picture, it's outdated but it's just more loops), but I have no idea what to do with them until the drywall goes up. I was considering a network enclosure, but there just isn't enough space in the stud section I pulled them through. I have 3-gang lv boxes.. skimmed that someone had used them but there was no example and I can't visualize it.

Second, electricians turned the house into a spider web of electric runs. There's zero chance of all of my runs meeting at 90 degrees. They also ran a RG6 drop to the closet through a cable raceway that has a lot of their electric runs (a few 110 and a 220). Essentially, how *actually* bad are close parallel runs with RG6 and unshielded CAT6 and electric? I'd really rather not rerun what's been done, but if it'll be a noticable quality decrease I won't have too much of a choice.

You can run the cables from the top of the stud bay/cavity to the bottom of the same cavity/stud bay and secure the low voltage box at the height you want your rack.

Tip: Once you get below the low voltage bracket use loosely attached zip ties the rest of the way down in the stud bay , this way you can pull the cables up and out of the wall easily after it’s sheetrocked.

Seems simple enough, thank you!

Welcome. Here is a more detailed answer

Hammer hook nails into the stud (make sure to hammer a hook nail within 4 inches of your main hole at the top of the stud bay, and hammer another hook nail within 4 inches of your low voltage box, and then hammer another hook nail within 4 inches of the bottom. Then run zip ties through the hook nails to secure your wires. Any zip ties below the low voltage box will be zipped loosely around the wires through the hook nail so you can pull the wires up and out when you are ready to terminate.

Basically just follow what the electricians do, but leave your stuff loose enough to pull back up and out the wall after drywall.

If you zip tie too tight you will have to yank hard to get one wire free then the rest will move easily, or you will need to cut Sheetrock to get your wires back out the wall.
