Very nice design, well thought out and easy to print. I hack your STLs to make a mini 4-bay (SFX power only) version as I do not have the room for the full version. Printed in black PETG without trouble. The chassis hosts a Supermicro x10sdv-6c-tln4f (Xeon 35W TDP). Temperatures are great with 3 fans at minimum speed: noctua 92mm for HDD, noctua 92mm for motherboard intake, noctua 140mm for interior. It is completely silent apart from the humming of the HDDs. Thanks for making this design. I love my new Freenas server !
