I would also like to know how to test the power supply. Sure I could buy another one from a good supply house per Dan's suggestion, but I have 2 here now and I know the outlet and cable are good (works with other PCs and iMacs). What I don't know is why I have no LEDs lit up on the motherboard. Can they be tested using a multimeter? Thanks.
This likely indicates a graphics chip failure and need for a new motherboard. Very common in the 2011 Macbook Pro series, but apparently also affects some retina display models too. Repair extension from Apple https://www.apple.com/support/macbookpro-videoissues/ Sadly they no longer repair the 2011’s.
It is not a total reboot, it just turns on the machine. That said, unplugging the battery and the power for a bit (30 mins?) should accomplish an SMC reset.
The Accepted Answer refers to a post which replaces the optical drive with an SSD so that the iMac has both an SSD and HDD. To answer your question, there is no 3.5" SSD drive form factor. What you want is a 2.5" SATA SSD, which you will place in a 2.5" to 3.5" adapter. Because of the length of the cables, you want one that won't just hold the drive in place but puts the connections where they belong, such as the Icy Dock EzConvert.
Good catch, looks like I misread the original post. I was responding to the sentence "In order to put a SSD into an iMac that isn't a 27" or a 2011 21.5" then you need a optibay." This is true only if you wish to retain the original HDD, which was the case, but as I said, I misread the somewhat awkwardly worded original post. That said, prices for 512GB SSDs are getting near $200 these days and will continue to fall. Considering the speed increase and reliabilty of SSDs vs HDDs, I am finding it harder to justify the cost savings of HDDs lately.
The top case is a bit different as well. The are screw holes for the subwoofer on the 2010 which the earlier model lacks, and the bluetooth antennae on the 2010 has a piece of metal that looks like it attaches to the frame (glued?). The older model has a thin black plastic material covering that area (which appears to be cut away on the newer one, but I couldn't find any info on removing it and didn't want to mess it up so I left it in place. HTH someone.
After step 5, I would skip 26-27, 34 and just to 46-50. You need to remove the cable from the battery, so even if you do 26-27 and 34, you'll need to do 46-50.
I use the solvent to remove the left over glue after the battery has been removed, but have been able to separate the battery by just sliding a card between the battery and case.
Just walk it out slowly. The cables don’t have a lot of slack, so if you pull too hard on the card it may yank the cables out of their sockets, or worse, when it comes free.
Parts of this guide are used for other guides, such as replacing the top case. But also, the speakers can be damaged by solvents, so it’s not a bad idea if the method you’re using has the possibility of getting solvent on them. It’s easy enough to just remove the screws and move the speakers out of the way without disconnecting them.
May not need it to remove the battery, but it sure helps for removing the leftover residue and black VHB that’s left behind. I found that dousing the VHB and using a metal flat spatula helped.
This step is easy enough that I’d just remove it to be out of the way. I 100% agree with your other comments though. While you’re here, might as well do step 21 and remove the drive, just takes a sec.

Safer? Probably. Easier? Not at all.
If you are here to replace the logic board, you can skip steps 12-16, they’re unnecessary to replace the logic board.

I just did one of these that didn’t have these screws installed from the factory. Odd
I think this is good advice.

Agreed, this is the way
