Upon it arriving, the seller (Woot) did an incredible job of ensuring that the Mac would be delivered in the same condition as it was sent.  Minor scuffing on the aluminum surfaces, as was described, and the screen was perfect.  It booted right up into the setup application, and after setting it all up I couldn't find anything to detract from a 5 star rating.  What surprised me the most is that the memory advertised was 8GB of DDR3, but what arrived was an iMac with 32GB of DDR3 installed!!  That was a great surprise, and after upgrading the mechanical HDD to a 1TB SSD the system is blazing fast and handles everything I throw at it.  It's currently upgraded to Monterey and I am very pleased with my purchase.  The included keyboard and mouse aren't the best, but with a little effort you can find Apple brand keyboards and mice from various sellers in great condition for a fraction of the price.
