X-Case RM 413 Pro

[Methanoid]

This case asks questions:

1) Why no cooling on the middle 3 HDDs?

2) Why only 3 HDDs in middle when the same rack from the LHS or RHS would fit and allow 5 HDDs (RM415 Pro model??)

3) Any vents in the TOP of the case? 2 120mm fans draw in cold air that 2 80mm will struggle to vent?

4) Are those handles silver or white?

5) What is the silver box in the RHS of the case at 12s into video?

Very interested in this case
