Any problems with resonance with the glass?
Is the mini-ITX case a wood veneer on metal? Or rather, how much metal is hiding in there? Where did you get the back piece? (Edit: oh, I just clicked your link and saw the rest of the photos. Very cool! I have an M350, maybe I will try something similar with a custom housing. Finishing my first wooden case, definitely nowhere near your skill!)
Also: What kind of workshop do you have? Do you cut/plane/join your own boards? Very nice wood!
It isn't glass. It is extruded acrylic. I'm not sure what you mean by resonance but nothing is resonating.
Both computers have an underlying stock steel chassis, one Lenovo and the other Cooler Master. I don't have a workshop. I mainly work al fresco.
