I just bought a H510i White and have not built it yet as I am still waiting on other parts. This is my first new build in 10 years, the case does look nice but I had a hard time picking to get a small case but still with good space. I always bought Antec and Fractal cases but i wanted somthing different.
I Did read the older H500 had good airflow if you added two exhaust fans and removed the front intake not the best but not the worst, I am busy trying to find replacement fans for that reason. I really wanted the phanteks evolv x but it was just to big and twice the price but that case did impress me alot as it looks like alot of thought went into that case, I could of bought it for the higher price it was just to big for me.
The other cases i thought about where the
Phanteks Eclipse P300 Glass Midi Tower Case - White
PHANTEKS Eclipse P400A Midi-Tower, Tempered Glass, Drgb – White
as you can see i never owned a white case, lol and wanted somthing different as i have had black & gray cases for years.
I bought the BE QUIET Dark Rock Pro 4 to go into this case and its tight i can tell you as i read that the hight is 162.8mm and the H510i can take up to 165mm as this is the 2nd best cooler you can get apart from the noctua which needed new black fans and the colour plastic plates to hid the meatal color which added about 50% to the price and decided not to bother. I was not to ken on water coolers, they do look good in cases but read that they dont last and somtimes leak if your unlucky.
we will se what its like as a 3900x and Vega 56 sapphire is going into this case.
