Thanks for the replies. I chose that particular fan because I heard it was quiet, and could handle overclocked cpus, did I hear wrong? As for the motherboard, I know they're are better choices, and normally I would have gone with them, but I'm on a budget for this computer. I would love to see the guide that was mentioned earlier, but the page won't load. Can anyone tell me if the memory I chose will get the job done? I'm kind of clueless in that area.
It's not overkill because you can overclock the memory only, but i really don't know if that 7700 will hold up to what you wan't. Since you are building a HTPC i don't know what You will need to see if a better heatsink fits for your case.
a Zalman 9700 is a good choice, but also is a Scythe Infinity and a Thermalright Ultra 120.
