Pretty much all Z370 boards have been added now. The only ones left (as far as I know) are three boards from EVGA. I'm waiting until they release better specifications (e.g. the manuals) and better images. If that doesn't happen in another few days I'm just gonna add them as is.
Now back to the adding the bazillion older boards that have been released over the many years. It's gonna take a loooooong time until that is done (if ever, without any help...).
