Peavey cab update

I got the big panels taken out of the divider (why did they use OSB for the baffle and back but ply for the divider?!) and "Swiss cheesed" the material I couldn't rout out.
I don't think I'll drill holes through the other braces unless I get really bored. To be clear, this does have a purpose: not only am I removing weight from the cab, but I'm also increasing the volume of air available inside the cabinet. The front-to-back internal dimension is actually only 9 5/16", so without any bracing or the speaker I only have a maximum of 2.9 cu. ft. to work with. Cutting big holes is obviously great, but cutting 3/8" jokes in 3/4" square braces? Probably not so much.
Also, not going to lie, six year old me was really happy doing this.
I have most of the braces cut already, so the next step is screwing and gluing them in place. Not really looking forward to trying to tune the shelf port. It's so big that the length calculations are fairly insensitive to minor variations, so hopefully it won't be too bad.
