Well designed

A mostly well thought out design with good cable management. Documentation could be better. The header adapter for power, LEDs etc culd be better too. Not able to connect everything on the ASRock ATX motherboard I purchased but at least all essential connections can be made.
Love the drive cage assebmbly - very easy to swap out drives if needed.
