The iMac in many senses isn't a replacement for a proper desktop. You can't expand the disk storage, many iterations had no great graphics cards, this seems to be somewhat better now, but an upgrade means having to upgrade everything, including the screen. You can't even clean out the fans after some years. Yes, I own an iMac, as this is the closest to a desktop machine Apple sells, but a replacement for what the Mac Pro used to be, it is not.
