10 x Stackable 3.5 Inch Hard Disk Drive Mounts with 12x12cm Fan Attachment Holes

For 3.5 Inch Drives (101.6 x 146 x 25.4mm)

I used 5 x WD100EFAX to design and test these mounts

A 120 x 120 x 25mm Fan can be mounted every 4 or 5 drives

If you add a fan every 5 drives there will be a 13mm gap between every fan

If you mount a fan every 4 drives there will be no gap between the fans what so ever

You will receive

10 Plastic Mount Pairs (Left and Right side)

You will need:

HDD's themselves

120 x 120 x 25mm Fans

M3 Hex Allen Key

4 x 6/32 HDD screws per drive

PLEASE NOTE, IN THE IMAGES ATTACHED, I USED BUSHING AS SPACERS FOR THE FANS SO THAT THEY DO NOT TOUCH THE DRIVES

SINCE THEN I HAVE SIMPLY EXTENDED THE MOUNTING PIECES BY 5.4MM (THE SIZE OF THE BUSHINGS) SO THAT THE BUSHINGS ARENT NEEDED

MAKING EASIER TO MOUNT THE FANS
