modified plan...I know I'll get hate mail for saying this but I consider putting a router inside a box a risky move with few to no benefits and potential problems. You did a great job, it's just something I would never do and feel strongly about.
+100 I had my kitchen remodeled a few years ago and did it with nothing but drawers on the lowers. What a difference. No more kneeling down and bending over to find something at the back. I have done the same in my shop. While it takes more work, the results are well worth it. Best to get full extension slides.Like the cabinet. Also think drawers would be better than shelves. Easier access.
