The iMac 24" (M1) earns a 2 out of 10 on our repairability scale (10 is the easiest to repair):

The fans, USB ports, headphone jack, power button, speakers, and webcam are all reasonably modular and fixable in a pinch.

The external power supply is trivial to replace, but very difficult to service.

The display is tedious to remove and replace, but it's the most accessible component.

There’s no altering the internal storage—a severe blow to repairs, upgrades, data recovery, and even security.

Memory is soldered directly to the M1 package, making it impractical to ever replace or upgrade.

The only path of entry is through the display adhesive, making all repairs tedious.
