800d USB 3.0 upgrade kit???

I guess sometimes procrastination has repercussions. Normally I get by just fine, but now that I finally decided to hook up my front panel on the 800d I bought upon release in 2009 (never had a use for the front panel really), I discovered that a 3.0 upgrade kit had been released a while back. Unfortunately, none of the sites listed as having them in stock on this site actually do. Does anyone know where else I could look, or did Corsair simply stop making them due to a lack of demand?



Thanks!
