Maximum PC: MSI's new Adora24 all-in-one (AIO) PC is supposed to be a treat for your eyes in more ways than one. To start with, it's an ultra slim system that measures just 21mm at its thinnest point. It also makes use of "staggered lines" to make it look even slimmer, MSI says. Not only that, but the flowing lines down the side are supposed to enhance the feeling of "crisp speed." Yep, MSI's marketing gurus had a field day with this one.
