PSU with full flat cables (semi modular or full modular)

Cause top vent is dust magnet and doesn't really help with temp.
As an exhaust it shouldn't be a dust magnet if intakes have filters ... also it helps greatly with thermal buildup around cpu area when it's used as a second exhaust

In theory, yes. But I have had cases with top vents which accumulated dust far faster than those without it.

I do not deny that the top vent is beneficial. But it is more of a marketing gimmick for me. A PC running at 70c is not going to perform better or worse than one that runs at 50c.
 
Your case looks like a rats nest. Flat cables can do so much more.
