Case Build Help

[JPBruwer]

Hi All, new here!

Would like some help with Airflow for my new design. Its not much, but what I am essentially doing is building a box, which would initially be on a drawer style rail under the one side of my desk. I have some drawings, and need opinion on which would work best for airflow, and some considerations..

Blue arrow is air intake, red is out.
