I was Hesitant in buying a later model computer, however, this IMac is able to update to the most recent software available and you are able to replace or install more Ram with ease as there is a door for it rather than having to have a tech shop replace. The green and body was flawless when opened. The keyboard and mouse are not apple products, however I did expect that so I already bought an apple keyboard and mouse in advance. The computer is smooth and beautiful. If you are on the fence of buying this model I hope this calms your worries!
