need HELP will this system be fine with ubuntu and xbmc

Nice, you can just get a single 4gb stick and you won't notice the difference.

Even if you get a 2gb and it will run fine.

-$20 AR for a Corsair CX430 and you will sleep much better at night.
-Better RAM, same price (yes it will work even though Llanos can only do 1333 officially...):
-Cheaper motherboard, better user reviews (take with a grain of salt) though it has less SATA and less USB ports:
-Better case, cheaper, better airflow case with 2 120mm fans and USB 3.0 ports:

only problem with that mother board is it has no hdmi .

Adjusted the motherboard. It's only about $7 more since you get a combo with it now. New mobo is full featured including Optical SPDIF audio, E-SATA, etc.

I am in the same boat in building my first HTPC. I am going to be running Windows 7 Media Center and planned on adding an HD Homerun to the mix. Which would be better for my needs. The above post or what I came up with...

Thanks!
