The case is an Antec ISK300-65. It came with an internal 135 watt PSU, but the power brick is only 65 watts. I've found inexpensive new bricks that will put out 120 or 135 watts and am considering upgrading there.
The next question is, if i get the 120 or 135 watt power brick, can it work with a triple core A6? Or should I go the Intel route? What CPU/mobo combo would work best? I have an HDHomeRun, along with lots of H.264 movies, and enjoy watching Netflix in HD.
If it came with an internal PSU, what is the power brick for???
Perhaps you are talking about Llano. Yes, but Trinity A6-5400K is a better choice.

The E-350 is weak at best and having the latest video drivers with NO POST PROCESSING selected in the CCC will serve you best for that processor. Upgrading to an eSATA enclosure (assuming you have the connection on your mobo) would help. Upgrading to an A6 means a new mobo and possibly RAM which is essentially a rebuild. Funny you mention .264 movies 'cause I find the GPU knocks them out with ease - see how your APU is performing on them with MPC-HC - it's a free d/l and is DxvA accelerated. Grab the AMD fusion apu monitor to see how much CPU/GPU is being used.
