asus p4c800e deluxe with slk-900/tornado

I am getting the asus p4c800-e deluxe and also getting slk-900 sink. I have a couple of questions before I order my stuff. I am pretty sure I'm ok but wanted to check and make sure.

I am getting the tornado fan for my slk-900. I need to get a controller to tame that beast down. I am also looking at the vantec nexus nxp-101 to do the job since I need front mounted usb and firewire. Here are my questions.

1) That fan speed controller only has a 3 pin power connector. Will there be any problems with using a 3 to 4 pin adaptor?

2) Everyone seems to like that particular controller except that they are complaining about the fact that the usb/firewire connectors don't have a motherboard type connector, but rather just standard usb and firewire "external type" plugs. I am thinking about just unscrewing the usb and firewire port from the external slot cover included with my motherboard and just making them internal so I can connect the ports with running the cable out the back and into the external connectors. This shouldn't be a problem will it?
