Hello Jonas,

You do not need to worry about high fan spin on this model. Just be careful swapping the drive and you’ll be fine.

Standard capacity of the PCIE SSD is 128 GB. Replace your Hard Drive with a Sata SSD for the best price per performance. You can then re-fuse both drives and format to APFS if your running High Sierra or higher.

Hello David,

There is no M2 slot on the Logic Board. It’s actually a PCIE slot located on the inside of the Logic Board. It’s possible but not really worth upgrading the PCIE card as Sata SSD prices are getting pretty cheap. Install a Sata SSD and fuse the drives together.

Both the iMac 5k and Surface Studio have a repairability of 5/10. Looks like they have the same build qualities with both cop outs being the %#*@ display assembly.
