Is it a standard SATA port in there that will happily accept any regular SATA device, or will I need an adapter of some sort? I know about the mounting frame, just asking about the SATA connector/interface itself.

Alternately, does this model allow booting from the SATA port the SuperDrive is connected to, in case I choose that route?

(ps. sorry, I just found the correct forum to post this in - mods can delete this thread)

From the experience of my iMac 24" early 2009 (similar to your iMac 20", but with bigger display)
- The internal HDD uses standard SATA port, a SATA SSD will fit just right in. (I swapped SSD to my iMac 24" 2009)
- The internal ODD uses laptop SATA port, you will need to use a cheap SATA bay (or adapter) to replace the ODD with common SATA SSD. They are usually called "caddy".

I used to see those caddies offered at 2-3$, but they seem to be rarer now. Check carefully for the thickness (3 types of thickness available 7mm, 9mm and 12mm)

Thank you! For anyone else who may be wondering, I can confirm it's a regular SATA interface. I plugged a bog standard SATA SSD in there and it was recognized just fine. I simply reattached the HDD temperature sensor with a strip of double-sided tape, and used Macs Fan Control to regain some control over the fan RPM which was a bit off compared to the readings it gets from the original mechanical HDD.
