Scythe Big Shuriken seems to be the best available, however, I am a bit worried since I read user feedbacks from somewhere that it might block you from installing RAM because it sits so low on the motherboard.
Also, Cooler Master GeminII S RR-CCH-PBU1-GP seems to be the de facto CPU cooler for HTPCs. I am a little hesitant in buying this one because I am not sure if it will fit inside my SilverStone GD05B case. If anyone has experience with this case/cooler combo, please let me know. Thank you very much.
