My review of the Raidmax X08 open air chassis is live over at Tom's Hardware today.
We like the look and thermal performance of open-air chassis like the Raidmax X08, but you have to be able to live with all the dirt, dust and pet hair that gets into your system. Also, $240 seems like a lot for essentially a skeleton of a frame with a couple aluminum and tempered glass panels, especially considering you'll need to bring your own fans.
