This is my first-ever build, so please pardon the terrible cable management.
I fell in love with the H200 case for its sleek design and size (small enough to fit in the space I had, but big enough not to be overwhelming and frustrating while building for the first time). I love this PC so much and it is working really well so far! It runs The Witcher 3 at about 70 fps on Ultimate settings. Just what I was looking for.
The only downside I have noticed so far is that the GPU runs a bit hot. After having already purchased an ATX sized power supply, I learned that an SFX power supply is better for cooling the GPU in this case since the more narrow design allows airflow from the bottom of the case to cool the card. If I could go back and do it again, that's the only thing I would change. However, I got the power supply I am using for about $50 since it is Corsair certified refurbished (1 year warranty). It was hard to argue.
I actually uninstalled the top fan on the case (for now) because the motherboard only has one case fan header. I plan to get a fan splitter in the future and reinstall the top fan which I hope will help with cooling the GPU.
The idle temps I added are approximations, what MSI Afterburner told me as I was typing this. The "under load" temps are what I see on my MSI Afterburner overlay while playing The Witcher 3 on Ultimate (especially after playing for an hour or more).
