I used to use legos for air blown temperature tests of electronics. You just need to keep most of the air in, fit a few shapes of DUTs (hard drives, ethernet transceivers, etc) and not melt at 100C. Some vendors do not like the idea of legos used in a test setup. Some vendors don’t know a good solution when they see it.
