Color me interested, I love playing with server hardware, and I have electricity included with rent, it would be easy for me to provide a home and let 'em crunch away.
I wait about a month then install it.
While there may not be any day one issues, I'd rather not deal with them. My time is becoming more and more limited to tinker with things.
To use a car phrase, "There's no replacement for displacement." (in reference to engine size)
It will help, but its not going to be any kind of miracle for speed, it seems most things now love sheer size and not always speed of the ram.
M.2 on the bottom? I dunno how I feel about that, its something you don't always need access to, but when you do you'd have to take the motherboard out. I've built several mITX boxes, none had access to the bottom easily.
