How is the Phanteks - Enthoo Pro M Tempered Glass case? Anything better that is also $100 or under?
I have this case, I like it. Keep in mind stock it does not have many fans, I think only one rear fan so you may want to get a fan for the front. It was one of the few cases I liked the design of that had optical bays.
M.2 drive on motherboard then, no need for SSD mountingMy only real complaint with this case was that the front-mounting SSD feature was a bit of a pain to work with especially using front-mounted fans. You have to do a bit of creative cable management to get it to look right without obstructing your air flow. Otherwise this case was a dream to build and upgrade in.
