For those not interested in a sleek computer enclosure like the SilverStone Temjin TJ10, a humongous chassis like the Cooler Master ATCS 840 EATX, or a professional-oriented chassis like the SilverStone Fortress FT01, there is the Sunbeam Acrylic UFO Cube Case. The Sunbeam Acrylic UFO Cube Case is a do-it-yourself case that is made almost entirely of acrylic and will allow you to show off all of the hardware you have installed.
