Questions about Apple iMac Retina

7th Generation.

Hello Patrick It is practically impossible to install an SSD on your own, as you have to remove the entire display. Therefore, if you want an SSD, I recommend ordering it directly installed. I have the 1TB version. As a web developer, that's enough for me and I prefer to have more memory. The 2TB also has a double-sized SSD on it. Speed-wise, however, my MacBook is faster with a pure SSD.

I would definitely recommend 16 GB. The slots must be evenly distributed, so 2 x 4GB for example, as you wrote. Here is more information: https://www.datenreise.de/imac-retina-5k-arbeitsspeicher-ram-aufruesten/

Yes.

This works without any problems. However, it would be advisable to supplement the (slow) fusion drive with an SSD. In other words, boot from an SSD and work on it. This is especially worthwhile for intensive reading and writing work.

Apple supplies all iMac's with a stand for placing on a table. To mount it on the wall, ask a carpenter. Perhaps a shelf of a bookcase will do.

Lightroom and Photoshop will not be a problem. Games are possible with restrictions. With limitations means that most games are developed for the Windows platform and not for mac OS. Therefore, there may be limitations in the selection.

Correct. This is a mid-2017 model.

Good day I also bought this iMac and a short time later I increased the Ram s to 2x16GB. I have installed the following rams: HyperX Impact (1x, 16GB, DDR4-2400, SO-DIMM 260 pin) I can only recommend them, they work perfectly, old ones out, new ones in!
