Open-air Cases for GPU Mining
Open-air cases are designed specifically for scrypt (GPU) mining e.g. Ethereum, Litecoin, Dogecoin, X11 (Darkcoin)/X13 (Marucoin), etc., where the GPUs are mounted over the motherboard (via riser/ribbon cables) and widely spaced for optimal cooling.

Tech Trays
I designed these simple, all aluminum, heavy-duty, open air trays for folders, benchers and miners. With the optional “floating GPU’ support beam, these become the perfect open air case for Bitcoin/Litecoin mining rigs.
The stackable trays can be used to create a space efficient computing “farm.”
