I may even provide an optional alternative rack designed to hold SSD's, I'm just not quite sure of the dimensions at the moment. I'm pretty sure air flow would be more than adequate and you could always fit a 160.1 rad in front of that 200mm fan if you really wanted to???
your design is greagt but mick64 is right, 3.5" only bays are outdated 5.25" are much more flexible

additionally i don't know ANY high quality 200mm fan out there, it'll be quite difficult to source a fan of this size -> 2 120mm are a better choice

maybe it's possible to make a 3.5" and 5.25" bay with a blanking plate for the 200 mm fan once youn install the 5.25" bays

it would be a great feature and VERY flexible
