Question Can any of the Define or Meshify Fractals can be optioned with sides with fan + mesh instead of glass?

[All Out of Bubblegum]

What about Phanteks Enthoo/Pro and Eclipse series?

Do you mean a mesh side like the Fractal North? If so, that is literally a new feature, its possibly fractal will add it to later Define or Mesh models but right now its just on North.

No idea about the other makers.
