Thank you for your quick reply !
For question A regarding the PSU, I was thinking of using a product from Thermaltake (Thermaltake Mini ITX Drive Bay PSU) instead of going through the whole PSU replacement.
For questions B...I don't even understand what I said. A note to proof read so I apologize. What I was trying to ask was "Does the PCI-e power cable that comes out of the PSU powerful enough to power the Video card as well as everything else" The machine is putting out a lot of heat as it now and I am lead to believe that the video card is not receiving the optimal power that it needs.
C) The cable that came with the video card is short and I need another.
