How can I make a 970 work in a mini-ITX build? Also, what's the least coil-whine 970 version available?
Full size GPU's fit in nearly all Mini-ITX cases just fine.
Pic related is what i use.
But as other anons said, there is a mini-sized GTX 970, which will help keep your build less cluttered.
Anyway, i would reccomend going Micro-ATX. Cable management can be REALLY FUCKING SUCKY in Mini-ITX unless you're really experienced with it.
My case looks like shit on the inside. Cant wait to upgrade to a bigger case.
Temps are all fine. The case has satisfactory airflow. I never OC'd it or anything though.
In the end - if you dont plan on moving your PC around constantly, dont get Mini-ITX.
The biggest problem is that the cables that come with PSU are about 2-3x longer than they'd need to be. As a result, your tiny case ends up stuffed full of cables.
Also, YOU MUST HAVE A FULLY MODULAR PSU!!!!!! When i first built this, i used a shitty non-modular PSU, and i spent a solid 2 hours trying to cram the excess cables into empty HDD slots so i could get the case closed.
