Within reason, USA. I've been looking ta all the usual suspects from Corsair, Fractal, Antec, Silverstone. I'm thinking maybe just mounting a 120mm as an intake high in the back (standard exhaust location) and exhausting out the top with instead of the back but I'd like to assume there is some engineering put into the design of today's cases and that that may not be the best air flow. This is why I was thinking of mounting it in the front. Plus I've seen many cases with dual 120mm front mounts and an air filter. SO... I'm looking for a case that I can mount something like this up front as the main intake with enough tubing. Although it does occur to me that this would mean that I'd need another intake still somewhere to draw in cooler outside air that hasn't passed over a radiator. Bottom intake perhaps. I could also do a single 120mm if I can fit a second intake fan to cool the harddrives that I assume will be up there also.
Look to make things clear just consider the parts in ur case that generate most of the heat
Personally in my opinion u can do one thing
1.place the rad at top and put a powerfull high airflow rear fan as to provide coolfresh air to rad
2.place the bottom and intake fan as intake to provide airflow to gpu
3.place a strong fan as exhaust on side to take out gpu hot air
