I don't think I'll be changing my fans on my case, I just was wondering what, if any benefit it would have, to have all exhaust fans.

I currently have a back and top exhaust fan, as well as two intake gpu side case fans and a Cpu intake side case fan behind the mobo.

I have four slots open for fans still that Idk if I'll use anyways, unless it becomes necessary to fan my Ssd/Hdd... Two are on the front panel, two are right behind the drives in the case.

I was mostly just wondering though, what kind of effect having more exhaust than intake would have?

Is it just something I should test?

The flow is the most important.
If you can get good flow with all exhaust, it will be fine.

But the higher the pressure inside the case, the better the heat transfer.

This will be a small difference with computer fans,, but it only takes about 4, or 5 lbs pressure to make a big difference.

This is why they make pressurizes firebox boilers, as everything else about them sucks.
The worst part, after they are a few years old, they leak poisonous gas.

They wouldn't use them if they weren't efficient.

One of the coolest cases I have has 3 inlet, and no exhaust, except for the power supply.
