get the tsunami, itll still be heavier than those tiny media centers, but its all aluninum, so only ~25lbs fully loaded tops. plus itll alow you to OC and have lots of room (those itty bitty things are a ***** to build) also get the ultra-d, its $10 more than the one you picked before http://www.newegg.com/Product/Produc...82E16813136152
if you have an extra $50 past that get this ram, its twice as much, OCable and on special $40 off, great stuff http://www.newegg.com/Product/Produc...82E16820231021
P.S. neither of the companies are better, they fight each other for the top spot, which is good, means cheaper for us, right now tho, AMD and nVidia do seem to have the edge.

which.... ****, puts you about 200 overbudget sans kb+mouse (assuming you have speakers/headphones). if you can scrimmage an extra $200 (man i say that alot recently) youll get a great rig.
All prices courtesy of newegg, but thatll cost you even more. :/ man they should really deliver internationally, could make a mint. got a friend in the states? itll probly cost less in shipping (unless your in australia) then you save
