Also is mATX preferred over ATX? Haven't built a PC in over 10 years so I'm kind of re-learning things.
Having built with both on AM3 platforms:
Team and Kingston so far play far better on the value/mid end line of DDR3 memory, if planning to sink more on RAM i would begin to look to CL7 ones ^^ Form factor is not set in stone i.e user could decide
A sub 500$ PC with a AMD Phenom II X6 1055T
That sounds kinda CPU skewed - Defenitely not a balanced PC anyway.
But okay, if the main task is encoding, and gaming is not a concern I guess it doesn't matter
Exactly - the reason u can get a bang for buck *solution* is investing on areas that matter the most/reap most gains while not throwing needless money on areas that are irrelevant for the task on hand ^^
Thanks for all the help and advice. Got my rig up and going last night. It's blazing fast. I got all the parts you suggested except I got a 6 GB RAM deal from Fry's (it was Crucial RAM like you suggested) for $59.99 after rebate.
This thing runs Windows 7 x64 great and at normal clock speeds doesn't get too hot. It is a perfect budget build for video encoding purposes.
