I use the same one he's talking about:
It is perfect because it will hold your Corp and Runner decks as well as all token in the back slots, its made of durable strong plastic but won't "shatter" cuz it's not that that kind of plastic and it is flatter than the other "thicker" deck holders so fits better in a backpack etc. It is also a really nice friction fit lid that won't pop off and spill your cards everywhere.
I'm using the binder pages u/ImNotDareDvl linked to for collection storage and for deck storage I got this deck box last week as an experiment: https://www.amazon.com/gp/product/B0041EV4GK/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
It's constructed just like one of Ultra Pro's jank plastic deck boxes, which I've never been a fan of, but it fits 2 sleeved battle decks and easily holds bot cards in top loaders (assuming you're using 3.5 x 5 top loaders) for both decks in the larger space behind them. Only lacks storage for dice/counters.
