I have been using this for a little over two weeks with no problems. It has been updated  to macOS Ventura. 13.0. I made 1 upgrade that has really improved the performance. This mid-2017 iMac comes with two Thunderbolt 3 ports. I purchased an Acasis Thunderbolt 3 enclosure for use with a 1TB WD NVME SSD to use as an external boot drive using 1 of the TB3 ports. After restoring the internal iMac HDD drive to the external SSD I switched the iMac to boot from the external drive. Now boot times from power on to login take about 15 seconds not the 1 minute 45 seconds it took from the internal HDD.Using the Blackmagic Speed test the internal HDD was glacially slow consistently delivering read-write speeds of 97MBs. The external drive consistently delivers read-write speeds in the 2290MBs neighborhood. The memory is still 8 GB. I'll probably upgrade that before long.
