My father has a late 2013 IMac 27". Is it possible to upgrade cpu?

I am wondering if I can take off the screen and upgrade all the hardware in there. CPU, RAM, SDD. He loves the display but the I-5 and older SSD just aren't cutting it. Hoping to get him up to an I9 or R9. Is it possible to find a chasis that would fit the display so I could custom build it for him? Or find a chasis that will power the display and build him a tower?

Does Apple offer any easier hardware upgrade options?

The CPUs you listed don't use the same board or chipset so that's a no.

Since you already have the SSD you could max out the RAM but that's about it.

Also no to the chassis idea.

I am Really Sorry Because You Can't upgrade Imac 2013
It is not possible to upgrade the RAM in the "Mid-2014" or "Late 2015" 21.5-Inch models after initial system purchase at all

All the 27" iMac models offer

by mrmacfixit Moderator In reply to Is this your machine?

user upgradeable RAM (up to 32GB) and/or replacement of the HDD with an SSD.
Removing the screen is not just undoing a bunch of screws, it's glued in and takes a fair while to remove. (doable though)

Graphics and Processor are not upgradeable.

See for repair guides for this iMac, EMC 2639
