After trying out dozens of different ways of trying to store and organise my miniatures I have finally come up with something I am happy with.
One of the greatest features is that it is heaps more cost and space effective than previous solutions I have tried.
May I present the A4 Intimate Tray (weird name I know) ~AU$25 from Bunnings (our big hardware/gardening chain) in Australia but surely available in other countries.

Epic wise almost everything fits. Reaver titans fit but Warlords have to sit on the shelf to the side.
My 40K space wolves infantry previously were in an expensive extra large carry case with 48 foam cells per tray (4 trays) due to having to cut out larger cells for terminators and bikes etc. It now fits into two draws.
I recomend sanding the bottom of the draws or sticking something to them so miniatures don't slide around.
After that you can pull entire draws out to move fighting forces to the table top battle field and transport them by dropping and old cloth rag (I use cloth nappies) on top so they don't bash about and get wrecked.
I am finding this more gental on minis than the foam boxes as I would always have sharp things catching and weapons snapping in these systems.
