To clarify I meant one cube of that shelf (where it is currently in two). I don’t think you can fit the game in one box. Mine is in one of the game boxes and then all the minis in this: https://smile.amazon.com/dp/B072K5HF25/ref=cm_sw_r_cp_api_glt_fabc_JM201JR4ZBHVNS1KPN9S?_encoding=UTF8&psc=1
For me personally, I use a Feldherr box for my minis. I havent gotten around to downsizing my cards yet. This one box fits all of season 1. Not sure if I will buy 2 more for season 2, or see if Feldherr will create something more specific.

For the first release, I have all the non-mini components (with the cards sleeved) in the Kickstarter box. I have all the minis in one of these: https://www.amazon.com/gp/product/B072K5HF25/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
I haven't received X-Men yet, but I plan something similar. I'm going to try to fit all the minis in 2 of those boxes I linked, except the sentinels and maybe 2-3 oversized characters like Mojo and Brood Queen... For the oversized characters, I'm planning on cutting a custom insert in foam and storing them in an X-Men box and then putting all the other on components and cards in 1 box, like I did with the original release.
This will get me down to 4 Boxes of minis and 2 boxes of components/cards for everything. It is a lot, but this game has a ton of stuff.
For some of it I get these Feldherr boxes for 40 bucks off Amazon. The rest of my stuff I just have cardboard boxes with the top cut off and the bottom taped and I have some foam sheets cut to place on around the bigger stuff and keep it from moving. The 100 with large pluck can fit gaunts, the pluck can fit hive guard, broodlord, ect. The large base ones can fit genestealers and warriors. https://www.amazon.com/Feldherr-Storage-miniatures-tanks-monster/dp/B072K5HF25/ref=sr_1_1?ie=UTF8&qid=1541472600&sr=8-1&keywords=feldherr&th=1 https://www.amazon.com/Feldherr-Storage-miniatures-tanks-monster/dp/B07FFV371X/ref=sr_1_1?ie=UTF8&qid=1541472600&sr=8-1&keywords=feldherr&th=1

Throw in the map tiles from etsy (that avBernate mentioned)
And one of these (with a custom insert) for all the cards (premium sleeves):

2 of these for campaign books and for the individual unit expansions https://www.amazon.com/UniKeep-Ring-Binder-Clipboard-Enclosed/dp/B0195L5SKG/ref=sr_1_5
And finally one of these for all those single expansion sheets (and for the campaign books): https://www.amazon.com/Clear-Heavyweight-Protectors-Gold-Seal/dp/B07D6XLNY3/ref=sr_1_3
I still have to take the campaign books out of the above sleeve, but it's one way to hold on to them at least.
