Yup. I've had my 2015 5k iMac apart a couple of times, and it's not for the faint of heart. Screen is glued on, takes a few hours, and for certain tasks the entire computer has to be taken apart. Nothing like the drive swap on my mom's ancient 2008ish (?) iMac where you just suction cup the screen off and the drive is right there. I accidentally ordered the 'wrong' iMac (256gb SSD) which turned out to be the right option because the fusion drives seem to have issues. Had a 2TB SSD hanging off the back for the past 6 months until i finally went to install it internally. Sadly, if you didn't order your machine with a SATA drive, it doesn't have a SATA Cable -- hence having to disassemble the entire thing to get to the plug on the logic board that lets you add a drive.
