We can have separate threads in the various series sections for specific cases and build-ups of them, but I wanted to create a single thread here to record the known sources for the cases used in Trek (mostly in the TNG and post-TNG era). Several of these were used across TNG, VOY, and DS9, and even the TOS movies. My goal here is just to create a catalog of their real-world found item sources.
NOTE: This opening post is a wiki. Anyone can edit it. If you know of a case source, please add it here!
Jack Crusher Case from "Family"
This is an "Andiamo Aerospace bag"
The Daylen Quaice bag
Also the salvaged Borg component case from VOY "Timeless"
A Zenith "video movie" camcorder case
The "long" carry case
This was a carry case made by a (presumably) third party and then commercialized by Dynasound
There was also a Gameboy version without the lines.
It has had many incarnations across various series.
There is a great thread over at the TPZ on it.
The "Conspiracy bug" case
Picard's briefcase from "Starship Mine"
This is a "Clik Case" CD holder
(I think this pic in my notes was swiped from @Buddahaid at some point—I hope he doesn't mind. )
Geordi engineering case
The Dynasound organizer, a particularly hard-to-find item:

Thanks to Don Hillenbrand for this info!
TNG era Travel Hairdryer case
These little cases were used throughout TNG and into Voyager and Insurrection. They came in many guises and were used in many ways on the shows. There's a thread with more info here: http://discuss.fleetworkshop.org/t/the-conair-case/280
Starfleet Materiel Supply Command box
Also used on Enterprise:
Deep Space Nine weapons locker
Seen in "Hard Time" (any other episodes?)
The lock on the front was also used in "The Passenger" (thx to SurferGeek for the lock ID)
