No maintenance, just batteries for my wireless controller. Don't get the rechargable battery pack, takes a long time to charge and is a pain in da pwet. No cooling too, sometimes I play for 3 hours straight, just make sure the unit is well ventilated. Games, average one a month. PC: the reason i got a console is because it's plug and play. No drivers to download, compatibility problems, system crashes...blah blah blah. Some video cards probably cost more than a 360.
