Where can I get the following wiring extensions & adapters?

I figured I would go all-Corsair on chassis components for this build, thinking that it would be a simple method to ensure compatibility between components.

Me: Do the various little things you sell like fan controllers, fans, RGB controllers, and RGBs all work with each other?
Corsair: LMAO.

So, now I need the following:

1. Extensions for the 4-pin RGB connector on the Corsair fans. I need 24 of them.
2. USB Adapters
   1. As far as I gather, there seem to be 3 sizes of internal USB connectors:
      1. Small (like the smallest USB connector on a motherboard)
      2. Medium (like everybody seems to use.... except for Corsair)
      3. Big (with the mechanical key top center)
   2. I need 3-4 cables that go from mini-USB to the big internal USB connector.
3. Favorite internal 6-8 port USB hub?

I use this inside my Corsair Carbide 400R case

I don't do RGB lighting... just Corsair SP120 White LED fans and the stock case USB3 connection I/O. One of my other builds uses the USB3 to USB2 dongle that came with my 400R, but that is limited use.... that case also uses a NZXT internal USB hub but an older model.

Warning, I come from the land of Polar Bears scavenging for Timbits on the Tundra.... That's a Canadian webpage
