Plenty of bit holders, but you can never have enough drawer space.

Do you happen to have the plans you used for this?

I'm not sure what I've still got around. This design is my own combination of the Kreg and New Yankee Workshop designs. I liked the Kreg design for having the dust collection setup inside the cabinet (the NYW design had an external Y fitting which would keep it from being close to a wall), so this has the U shaped upper big drawer to get around the dust fitting going down from the router enclosure. But I didn't like the Kreg design for the bit holders, so I stayed closer to NYW for that, plus I've got a small wire chase from the router enclosure over the right bit storage and out to the power switch on the side. And I went with the Kreg top/fence which I've been pretty happy with and it's on a piano style hinge with locking supports. The cabinet is on 4 double locking casters, so when they're all locked the unit is nice and heavy and stable - doesn't move. The only thing that's kinda awkward is that I've got a Porter Cable router in it pretty much all the time and it's every easy to ding my knuckles on the insert leveling screws when I'm trying to loosen/tighten the collet with the wrench, so I just have to be really careful there.

Best cabinet I've seen so far in my treasure hunting. I appreciate your merging of several designs. It appears you took the most positive aspects of both design and produces a very functional cabinet. It has all the features of the cabinet i hope to build.
