I took one for the team regarding price—but considering the machine itself was already $4,350, I felt the expense was justified.
That, combined with the fact that I'd have had to stand the Studio on end anyway to fit it on my desk...
It's a ZEERA MacForge Studio with a 200mm DEMCiflex Round Fan Filter.
Note that the actual flat surface width on the case is closer to 195mm, so if you elect to spend the money I did, either this or a custom 195mm round filter would be a better fit.
Sorry, I don't quite see / understand where the filter goes?
