I use my Phanteks Eclipse P200A case as a NAS, and the optional HDD cages purchased with it leave very little clearance for the power and SATA connections to the drives. With the cords pressed against the side cover, it was actually quite noisy for what would otherwise be an almost silent PC. These standoffs snap in and create an extra 10mm of clearance. You'll need longer bolts to attach each cage to the frame - I used 3.0x14mm. Printed in ASA for long term heat resistance, 3 perimeters and 35% infill (0.5mm nozzle @ 0.2mm layer height).
