That's the MT02, created by a Spanish company called ModelMaq, which caters to miniature-painting enthusiasts. It's portable and makes fantastic use of its interior space. The base elevates the models up to a better working height for the painter and the storage is generous. I'm especially digging the little flip-up tool holder on the right with the perforated top. If it's not obvious in the photo, the paint bottles are all stored by their necks and rotate around a spindle. Also note the swing-out light fixture up top.
Here's their MT012, which eschews the base but seems to provide just as much storage:
Sadly, it seems these items are no longer being sold, and the model MT012 isn't even on their website. I'm guessing the price was too high or the market was too small. But they're impressive pieces of portable storage design nonetheless.
