If the Mini cannot be in Target Disk Mode, can you put the other Mac in TDM, and connect it to the Mini and check if Alt/Option will let you see the OSX disk from the other Mac? Another option is to install OSX on an external disk - How to install OS X on an external drive connected to your Mac - Apple Support - and try to boot from it.
Are you allowed/able to run Apple Hardware Test - Using Apple Hardware Test - Apple Support ?
