I'm building up a few Mac Mini Servers (Late 2012). I will be upgrading the small internal drives (dual 500GB HDD) with either dual 4TB or 5TB Seagate Barracuda 2.5" drives, which are 2.75 x 3.95 x 0.59 in.

It appears these higher density drives are a little thicker (0.59") than common sizes sold as upgrade drives for a Mac Mini (0.276" - 0.374").

A thread on the Apple Community suggests the largest size is 9.5mm (0.374").

Does anyone know the maximum drive dimensions that will fit in a Late 2012 Mac Mini Server?

As it turns out, 9.5mm (0.374") is the maximum size that can be installed without modifications to the Mac. Bummer.
