usb 2.0 vs usb 3.0 headers on case front

How complicated is it to yank all the 2.0 headers on the Cooler Master Cosmos II front panel and replace them with 3.0? I don't have the case yet (still trying to avoid paying $400 total when you add in godamn shipping for this beast), and would like to know how tuff and what I need to make this happen.... thanks if anybody knows...

You can use the 3.5 ans / or 5.25 slots w 3.0 USB adapter. Plugs into mobo, there ya go.....

yup you could get one of those or wait till you get the case to see if you can match up a generic panel mount cable to transplant in to the case. it looks like it uses something like this:

and this is what it looks like under the io panel:


but you will also need a way to plug in 3 more headers to your mobo or a controller card.

I grabbed the Kingwin KW525-7U3C

Using it with a Inateck Superspeed 7 Ports PCI-E to USB 3.0 Expansion Card (KTU3FR-5O2U)
