You will need to replace the USB2 ports if you wish to get USB3 speeds. Does your motherboard have USB3 ports? if so where are they? On the Rear, on a motherbd header, or both ?
I am getting an ASUS P8Z68 Deluxe mobo which has a usb 3.0 20 pin header and ports on the rear i/o .. so my question is can i refit the existing usb 2.0 on the case, to be usb 3.0. I am guessing there should be parts available for this purpose.
http://www.anandtech.com/show/4620/silverstone-fortress-ft02-true-classics-never-go-out-of-style makes reference to an aftermarket usb 3.0 kit, but I can only find drivebay versions, not one to fit where your 2.0's are at the minute, I'm also sure that will be a one-piece circuitboard so replacing that with a (possibly modded) drivebay version will lose you your headphone/ mic plugs
Google usb 3.0 drivebay if you want to check some of the options out, but at least you have the mobo or backplate option

I saw this review as well which made me wonder where he got that from I have not seen anything like it. I will keep looking, will post back if i find anything...
OK Found the answer on the of all places the silverstone website. Apparently on the ft02 page under q&a the question of refitting to usb 3.0 is asked and answered with full diagram and install info.. part number G11303260 go figure...
