Yes I have also seen reviews of the unit with the heatsink mounted towards the back of the videocard. I will attempt this myself and post pics, from my understanding it acutally has been said to improve cooling.
Look forward to updates to the review as I compile more data from other sources. Due to time constraints and my desire to post the review as soon as possible I went with what current information I already had on hand.
Thanks for taking a look
