Ultra Products Carbon Fiber case
 

The use of Carbon Fiber may seem excessive to some, but the light weight material reduces weight, which is great for those who frequently haul their cases around the country to LAN parties. It is these individuals that Ultra is hoping to entice with their new gaming PC's. Having lugged my heavy PC's around to more LAN parties than I can remember over the last several years I have to say that I'm pretty excited about the use of lighter materials.
