If you're looking for an easy way to raise your iMac screen closer to eye level, HiRise will do that. If you want a quick way to eliminate any trace that you use an external hard drive, or leave your keys and wallet on your desk HiRise will also do that. And because it's machined from aluminum, it will do so in elegant fashion.
HiRise can theoretically boost any screen, laptop, or All In One PC, but what makes it so iMac specific is the fact that it is built specifically to the dimensions of the iMac foot, and has adjustable height tray so that you can get your computer to just the right level. But slick looks and premium materials don't come cheap—this thing'll set you back $80. [TwelveSouth]
