Yeah, we have a similar setup for haberdashery - white Ikea Billys, a few extra shelves, and a lot of 9l RUBs. They're a couple of inches deeper than the shelf, but that's not really a problem. Larger projects and long-term storage go in 35l's or 64l's. The 84l's tend to be too big for us - we've got one, and I hate lugging it around.

That's a hell of a collection. Is there any risk of them degrading over time, as they're organic?

I discovered recently that IKEA actually do a deeper Billy that you can order online. I've seen them as deep as the Kalax. I used to work there and never knew. Might be helpful for the overhang

if they're the ones I'm thinking of (wide, but not very tall, good for large flat things - basically map drawers but not quite that big) just be forewarned that the drawers don't fully extend. (There are mods to fix that which involve doing some drilling and grinding on the drawer slides...)
