So, it's been a while since I followed computer hardware. Are the dimensions of room between CPU socket and DIMM sockets standardized yet?
I was thinking of getting this one for a 9700K build, but the Trident Z RGB RAM is 44mm high, which is more than the 38mm clearance I gather this one has. And while your test setup seems to have no visible issues as long as not all slots are filled, from looking at it, the distance between the DIMM sockets and the middle of the CPU socket seem pretty far apart compared to what it looks like on the Z390 boards I had a look at - eg. the Strix Z390-F. Maybe it is my imagination, but since I can't find any page stating measurements for the board I can't really check up on it.
Sadly, there apparently aren't too many aRGB CPU coolers, so this one is really attractive.
(not that I actually need RGB, but I also don't really care about the 100/200 currencies price difference for bling bling for the heck of it)
