Important parts: Thermaltake V21, 200mm fan, 140mm fan, GTX 1080 with a hybrid blower/140mm AIO liquid cooler, and a 280mm aio liquid cooler for the cpu. I figured I have three options:

1. 200mm intake on front, 140mm exhaust on rear, clear panel on top, blower facing left side vents, 140mm radiator sucking in air from left top, 280mm radiator sucking in air from right top... This is the option I feel would offer the best cooling, however I am concerned about condensation on the top clear panel.

2. Same as #1, however no rear 140mm exhaust fan, and the radiators would suck air in the opposite direction (from inside the case, blowing air outside the sides)

3. Front 200mm intake fan, left panel (by the blower) would be plexi-glass, rear panel would have 140mm radiator in-taking air from outside, right side panel would have 280mm radiator in-taking air from outside, and the 140mm exhaust fan would be facing upwards on the top panel between the two radiators.

Anyone have good reason to believe which solution would be best or have any other variants I have not thought of yet?

All in all, I'm thinking I will have to do several hours of stress tests in every variant to find the absolute best solution.

No budget, no more money to spend. This is for a friend who already bought the parts and is asking for my help in the build. If you must know the rest the parts being used they are: Ryzen 1700X, 2 8gb sticks of RAM with heat spreaders, 800w 80+ gold cert psu, and 1.1tb m.2 SSD. System might be upgraded with two more sticks of RAM and another hybrid cooled Gtx 1080 in the future

Christ, the 1TB SSD was a bit overkill, you really only need it for OS then HDD space, the rest can be spent on more performance! :)
Oh well, if he's already bought it then I can't stop him I guess.
Go for option no. 1, you need rear exhaust.
Given you don't have top mounting which would obviously be optimal for the CPU cooler, front intake will be fine, airflow won't matter as much since you have no air cooling.
You'll want some good high static pressure fans for your rads that are also quiet, get two Fractal HP-14s, fantastic for radiators.

Thanks for the knowledge. The only potential issue I can think with that is condensation. Those two radiators would be blowing hot air directly under the glass on the top with that configuration. That's actually why I was thinking of putting that 140mm fan as an exhaust, so that the hot air is pulled away fast enough to not have any ill effects such as condensation that might drip directly onto the MoBo. Or am I just worried about something that is impossible?

Also, you're saying that top mounting would be best for the CPU radiator and possibly GPU radiator as well? How so?
I could put the glass panel on one of the sides, and then mount both radiators on the top.

And would talk the guy into returning the SSD and getting a hybrid drive, then maybe buying another 16gigs of RAM or even returning the SSD and GTX 1080 so that he could get a 1080 Ti, for not much more than he already spent. However he is very keen on having the best load times in all of his games, not only OS boot up.

It should be fine, the air temperature won't get high enough to cause condensation provided there is at least some nearby airflow gate.

Top mounting is best generally because hot air goes up, so it is the most direct path of exit, resulting in cooler ambient temps.
This allows you to draw air from the front and exhaust it straight out the back.

So top mounting for the exaust fan. Option 3 would aim all radiator fans directly at the top fan, except then there's air flowing in from 3 directions before it goes out the top... Other option would be all radiators on one side. Hesitant to do this, only because that leaves one radiator low (next to the MoBo), and I don't know about clearance or the heat blowing directly onto the MoBo before it goes up to the exaust fan

I'm going to just do some stress tests in these three varients and maybe one more... If option no. 1 ends up being optimal, i'll be sure to give you credit of best answer

Either way I'll post temps of MoBo, CPU, and GPU after tests are complete sometime next week

Idm about best answer. ;)
Not about fake internet points, as long as you get the solution you're looking for.
What do you mean aiming all radiator fans directly at the top fan?
You'd need to have the fans on the inside of the rad at the front pulling air in btw, top exhausts sounds good as well provided there are vents there.
Keep the GPU rad as exhaust out the rear, that's good placement for it.
