Every tabletop general eventually hits the same wall: the army has outgrown the box it shipped in. Whether you are hauling a Warhammer 40k battle-ready force to a store event or slowly building an Age of Sigmar collection on a shelf at home, the case you choose changes how safely those minis survive the trip.
Two very different approaches solve this problem. One is a foam-based case you cut to fit your own models. The other is a metal tray system that relies on magnets instead of foam. Neither is objectively better, but they serve different collecting styles.
This guide compares the two directly so you can match the case to how you actually play, transport, and store your miniatures.
The 80-slot miniature storage case with customizable foam is built around raw slot count. With 80 pre-cut or trim-to-fit foam slots, it comfortably swallows a full infantry-heavy Warhammer 40k detachment, from troops to smaller support units, in one case.
The aluminum 5-tray case takes a different approach. Instead of counting individual slots, it offers five magnetic metal trays, each one holding whatever mix of bases you arrange on it. Capacity depends more on model footprint than a fixed slot number, which matters for Age of Sigmar players running larger monster or cavalry bases.
Foam customization is the headline feature of the 80-slot miniature storage case with customizable foam. You trim the pre-scored foam to match irregular model shapes, so oversized characters or awkward weapon poses still get a snug, dedicated slot.
The aluminum case skips cutting entirely. Its magnetic steel trays hold any miniature with a metal-washered or magnetized base, and repositioning a model is as simple as lifting and placing it elsewhere on the tray. That is faster for army lists that change week to week, but it does require your bases to be magnetized first.
Foam cases are typically lighter and more compact for their slot count, which matters if you are walking a case into a game store rather than driving. The trade-off is that foam compresses over years of heavy use, and once a slot loosens it can be harder to restore than a tray.
The aluminum 5-tray case leans into durability. A rigid metal shell and latch-secured trays protect painted models from impact better than foam alone, which is a real consideration for anyone flying to a tournament or shipping models to a friend.
At $99.99, the 80-slot foam case is the more budget-friendly entry point for collectors building out a first army box. It delivers a lot of dedicated storage per dollar, especially for infantry-heavy factions.
The aluminum case runs $179.95, reflecting its metal construction and magnetic tray system. For painted display pieces or a growing multi-army collection, that premium buys sturdier long-term protection and tool-free rearranging.
Think about total cost of ownership too. A foam case that needs replacing every couple of seasons because slots have worn out may end up costing more over five years than a metal case purchased once. Weigh the upfront price against how long you expect to keep collecting before deciding which case earns a permanent spot in your gaming bag.
If your priority is fitting the most infantry into one case at the lowest cost, start with the 80-slot miniature storage case with customizable foam. If you are storing painted centerpiece models or want tool-free rearranging, the aluminum miniatures display and carry case with 5 metal trays is the sturdier pick.
New Warhammer 40k players building their first army box tend to gravitate toward the foam case because it is affordable and holds a lot of troops. Painters who already have a magnetized display collection tend to prefer the tray system because it protects finished paint jobs during transport.
Age of Sigmar collectors running larger monster bases often find trays more forgiving than fixed foam slots, since a tray does not care about base diameter the way a pre-cut foam cavity does.
Club and league players who swap armies between events regularly lean toward whichever case lets them repack fastest the night before a game. That usually tips the decision toward trays for veterans and foam for newer hobbyists still settling on a permanent army list.
Yes, many collectors use foam for troops and a tray case for painted centerpiece models.
Yes, the trays are magnetic steel, so miniatures need a metal washer or magnetized base to stay secure.
The aluminum case's rigid shell generally protects painted models better against baggage handling.
Larger bases fit better in the tray system since foam slots are cut to a fixed size.
Match the case to your habits rather than the other way around: budget-conscious troop hauling favors the 80-slot foam case, while painted-army durability favors the metal tray system.
