Also since it's probably buried under all the OP stuff, here's my storage solution (These are old pics when we were up to Wave 5 and I had just created the OP - I have since expanded to three of these cases - one for each faction. I'll try to take updated pics sometime soon of what my storage looks like.)
To store my collection I use three of these:
Plano Double Cover Two Sided Tackle Organizer and I cut out custom sized trays out of cushion foam I found at Hobby Lobby with an x-acto knife (scissors to cut out the compartment shapes) to save some cash (a bit tedious but I'm happy with the results). A friend of mine went for
this one, which has various trays you can swap out depending on what ships and tokens you want to bring with you. It was a challenge getting my entire collection at the time to fit in one case, but I was adamant on making it work. Eventually I simply owned too many ships so I bit the bullet and expanded it to three cases, and I ideally wanted something that gave me the flexibility to store them cleanly, without moving around, so I went with the custom foam tray method you can check out in the pics below.
They are double sided cases that are symmetrical and have two layers on either side with plenty of space, even if you don't intend to go with foam like I did. I was actually able to fit every ship in the game up to until Wave 7 came out (not pictured below since as I mentioned, I haven't taken updated pics since), but getting every one of the large ships to fit at the time required some modification of the innards (unless you get more than one case like I ended up doing in order to comfortable store every ship in the game plus some duplicates), but one of these cases, with some careful planning, is definitely capable of fitting at the very least two factions worth of ships. When I purchased the Decimator and Shuttle when all that was available was Wave 5, as I mentioned, I had to cut/modify part of the innards of the case to get that Shuttle to fit with that layout, but I managed to make it work pretty easily with an x-acto knife. Here are some dated images of what my collection at the time looked like when I was using only one case (I apologize for the shitty quality photos, my phone's camera sucks):
Here's one side of the case, which contains all of the main tokens, templates, asteroids, and Rebel ship bases on the outer layer, and my Rebel fleet and movement dials on the lower layer. What's great about the foam layout I went with is that I have two stacks of 1 inch foam in each section, which means that certain flatter ships (like Z-95's, Y-Wings, etc.) can fit on the bottom layer, freeing up space. For example, in this picture I ended up putting a row of 3 Z-95's underneath the X-Wings you can see in the top row.
On the other side, I have miscellaneous mission tokens, two damage decks, mine and bomb tokens, space debris obstacles, and Imperial ship bases on the outer layer, and my Imperial fleet and movement dials on the lower layer. I also added side compartments using adhesive Velcro to be able to fit the large ship bases since I had run out of room (visible in the second image).
Since I eventually ran out of room for my case to store all of my card, I ended up storing them in a binder protected with sleeves. Nothing too fancy to see here (I have also since picked up a mini American sized binder to store the upgrade cards separately since my main binder was running out of storage space)
