With a slight modification you can actually install 4 of those modular drive bays in the V71 for a total of 8 drives running down the case. This is exactly what I wanted. I just need 2 more drive bays. I have been looking everywhere and cannot find anyone selling them. None found on Thermaltake Store except this one and it's not for the V71:

If anyone wants to sell the ones that came with their V71, please let us know.
Thanks,
