Working project cases/storage

So, Im limited on space and find myself forever having to move projects in progress around the house. It'd be nice to have a plastic box into which i could install a few breadboards... work on my stuff then shut the lid.

Unfortunately, my google-fu has failed me. Has anyone else done something similar?

Really Useful Boxes, at Staples, OfficeMaxDepot, online.
They have one that is not too deep, 4L size, good internal size, not too deep for reaching in over the sides.

I think this was the 4L box, with several 80x100mm cards mounted to the cover to hold my time & score displays.

That'll do. thanks!
