Engine bay management tips?

I'm not looking to work on this anytime soon, simply dont have time or money right now, but I wanted some other opinions on this. My engine bay looks very messy currently, with various dilapidated hoses and wires going every which way. The vacuum system is a mess, but intact enough for the engine to run. An unknown round part with (I'm assuming) vacuum lines and electrical connections coming from it is behind the air filter housing, looks ugly imo and am hoping it isnt necessary. As for the AC system, I'm leaning on taking it out entirely. The AC lines are unsightly as they are covered in rust and the rubber is cracking, and only adds to the messiness. The compressor itself is also rust covered along with much grime. Again, just looking for other opinions, thanks.
