ADDITIONAL COMMENTS:
Overall I want the system to be stable 24/7, able to run all my needs efficiently and with the possibility to go to OC/crossfire if I ditched the HTPC case. I know I might be asking too much trying to get design, gaming into an
HTPC but should be fun trying. I have been extensively reading reviews and more reviews. My choices are all based in a happy medium between Performance,Price,Looks and needs,
All Feedback is appreciated.
