I venture to say that not even covers / cases for gadgets can be considered necessary (good and recommended to have, but * necessary *, definitely not alone), let alone one for the base of your iMac.
Well, meet the iMac Slipper, which has just been released by the hard graft:
As well as other products from the manufacturer that we have already highlighted here on the website (1, 2), this one also combines the use of grafting with leather, providing a different and medium look in a ?farm? style.
Despite its name, the iMac Slipper is compatible not only with 24-inch and 27-inch iMacs, but also with Apple Cinema Displays. It costs 30 euros (just under R $ 70).
