Buy a used roll around tool box or a new one if you have lots of cash. While not a vidmar they can be just as good for light use. This especially since the advent of third party supplier of bins such as "

Generally you get a range of drawer depths so you can accommodate everything from capacitors to rather large steppers. The tool boxes come with wheels so that is a great benefit if you are out of wall space. Such tool boxes may be lockable also which may or may not be important to you.
There are other options but if you are already out of space they would require building a cart or other system to support small plastic boxes. With a custom cart you can configure in any way you want. You can use a range of bins like Ark-mils has but a self built cart (done right) requires a bit of effort on your part. An alternative would be to spend the big bucks on something like an arko-mils ProCart.
In any event if you think I'm obsessed with stuff on wheels you are right. If you are out of wall space you really want your bulk storage to be easy to move. Wheels make it easy to park things out of the way, use the storage on the back side and organize for a project.
