I think, with some careful planning and a little bit of modification you should be able to make it work. The pump/res combo is pretty compact, so there is definitely space to work with above where your gpu will be. One thing to be aware of is the middle dividing plate (where I mounted my res) sticks out just enough to slightly block a clean mounting of the res to the fans. There is, however, the option to remove the plate completely or to modify the bracket so it's offset slightly. I hope this helps and good luck with your build :)
The drive is great! I honestly don't hear it, and it's pretty quick as well.
Thanks for the kind words! It's definitely been a fun build (and not totally done...hardline tubing is in the works in the next week). To answer some of your questions, RAM is at 2933, it can hit 3200 on my Aorus board so I'm slightly limited by board,.. I have the CPU at 3.8ghz @ 1.3v and the GPU is at 1370MHZ. Overall temps tend to level off at 54C on both the gpu and cpu during a gaming session (idles at 30C). Eventually I plan on having a Vega (or Navi) gpu and possible a Ryzen 2 (3000 series) chip in the near future.
I'll be honest, I have no clue on the bit size. I pretty much selected the bit that was just slightly larger than the screw and then filed the hole a little bigger after that. It wasn't the most precise job I've done.
It just took some careful planning, a ton of measuring and 1 minor modification (drilled mounting holes for the pump). Despite it's size, the H200i has some decent room to work with. I honestly plan to add a 120m rad in the back, and replace all the soft tube with Hardline here in the next few weeks.
Very carefully, and with a few bruised fingers. Honestly, this is just the temp loop. My next step is Hardline and an additional 120mm rad in the back. :)
