Bleh, I would have said use a 2.5mm drill bit & an M3 tap for doing the skid plate to mount the CD unit, but it wouldn't add much strength really no- just be sure to use blue threadloc on all the screws for final assembly. It is looking very good so far, you can always touch up the chassis where you had to notch it using a red sharpie or even red lip gloss ( semi transparent effect like anodizing, so that you can see the metal surface texture but it is coated red ).
