So I'm thinking of picking up an NZXT S340 for a small form factor built, but I wanted to know if a long PCB graphics card like my Windforce 980 will fit with the cable cover/reservoir mount installed.
I actually have the same intention, the S340 can support cards up to 330mm+ in length, depending on whether or not you have a rad installed. So, yes.
Yeah, i'm going to be installing a H100i GTX in the case as well, the space for a rad+fan combo is about 60mm, so the 57mm H100i should be a very snug fit. leaveing about 8-10mm for the GPU. probably going to be a tight fit.
