if i were getting a new computer but didn't want to build it myself i'd go for this
http://www.overclock.co.uk/product.php? ... 3&view=relyes yes, it's overclock, we are overclock, but it would probably be better.
you can select all the components you want, so good memory (what's the bet that the mesh system has appalling value select memory etc)
so just fill your cart up with what you really want, add the system builder and you get yourself a working computer.
just as an example, on that computer you have listed, it has a creative x-fi extreme gamer, people read "x-fi" and think whoo, but in raelity the extreme gamer edition of the card is pretty crap.
