I use Ikea plastic containers. Bigger for motherboards and larger VLB/ISA cards. And smaller for ordinary size ISA/PCI cards. Sometimes I put the cards/motherboards in antistatic bags and sometimes I just put some newspaper sheet in between them when stacking. The usual cardboard boxes in proper dimensions are also fine. You can also use motherboard boxes, I usually put two motherboards inside.

Which containers specifically, and can I order them online? - no Ikea store in my area, thanks

I use these. Slightly over $1ea. I put a piece of foam in the bottom and have the motherboards in an ESD bag. 1 board per box, labeled accordingly.

I found these, and they're the perfect size. With my leftover Prime Day promo credit, they were just about $20. 🤞

I've gone with putting my spare components into anti-static bags and then putting them into plastic containers. Probably not the best way to store them, but it works.
