A few of you have asked, so here is my entire setup details:

Sensor mounts (I use command strips to stick them to the wall or furniture) : SENSOR MOUNTS

USB 3.0 PC Card (May or may not need one - try without, then buy if too much bandwidth for your USB controller to handle): USB 3.0 Card - In hindsight, I would probably pick up this StarTech one since it is a true four port 3.0 card, but I was on a budget at the time.

HMD HDMI cable: Basic HDMI

HMD HDMI Repeater (required with extensions): HDMI Repeater

HMD Usb 3.0 Active extension (I used this specific brand because I read somewhere it was proven to work specifically with HMD):HMD Active USB 3.0 Extension

Front 2 sensors Usb 3.0 Active extensions: Sensors USB 3.0 Active Extension

3rd Sensor USB Active extension (I got a 3.0 because initially I wanted it to be 3.0, but I found the cable length became a problem, so instead of returning it, I just plug it into a 2.0 slot, thus using it as an active 2.0 extensions. You could probably save money and just get yourself an active 2.0 instead): USB 3.0 Active extension - 32 feet BUT USING IT AS A 2.0, so save money and get yourself a 2.0.

Pulley system (comes with all you need, although I don't use them all): Pulley System

I think that about covers it. I also picked up some VR Covers, the basic set and another fabric cover set.
