In an e-mail announcement, Antec has decided that buyers of their latest cases who don't have USB 3.0 built-in to their rigs shouldn't lose the use of two USB ports. So, interested buyers can contact Antec Customer Support and receive an internal USB 3.0 to USB 2.0 adapter. This won't embue your rig with the great throughput those blue ports normally connote. But if two USB ports just wasn't enough for you, you'll have a solution. The text of the e-mail is below. 

To say we’re pleased with the response that the P280 and Eleven Hundred chassis have been receiving would be an understatement but we’re not settling. We have heard the feedback you and your readers have given us regarding the USB 3.0 internal connector. Specifically, some users who are interested in the P280/Eleven Hundred may not have this connector and wouldn’t be able to take advantage of two of the ports on the case.

As a solution, effective immediately, customers may contact us (http://www.antec.com/support (or 1-800-22ANTEC in the US) and request an internal USB 3.0 to USB 2.0 adaptor. All that will be required is a proof of purchase of one of these new chassis
