I see, thank you for the honest response! I think those wood patterns are a bit to complicated for the glass process we work with. How about keeping the panels totally clean and raising them 5 mm off the chassis? Check it out below:
Distance between panels and chassis is 5mm, 12mm to the PSU and 65mm worth of CPU cooler height (although 53mm is maximum recommended due to no cutouts).
I have to say that I don't love the panels being not-flush to the chassis. Any airflow which enters that way is going to have a lot of vorticity and will more than likely increase the noise profile for only marginal gains in cooling performance. It also reduces the aesthetics in my opinion.
I think that you either need to commit fully to airflow with a properly perforated metal panel, or the glass aesthetic and accept that the front, top and bottom will being doing the heavy lifting in the thermals department.
Edit: If the worry is primarily that the PSU would have insufficient cooling due to being so close to the panel, maybe finding a way to recess it into the chassis a small bit would help. Alternatively, what about something crazy like a 50/50 perforated metal/glass panel for the CPU side (glass exposing the mobo when you plan to run an AIO, and metal with holes to make sure the PSU gets fresh air)?
