good place to buy computer online

i have been looking for a good place to buy computers online but the problem is that i live in Iceland wich sucks, so i cant use newegg or ibuypower.com and since the computer i was going to buy sucks http://www.gamespot.com/pages/forums/show_msgs.php?topic_id=27320137&tag=topics%3Btitle

im asking you guys where i could buy a new computer im only 16 years old and will only have about 763 usd after the summer but i figure i could just ask my parents to buy the computer online and i'll give them the money

(p.s. the only reason for the computer will be gaming)

Id say the best option would be ordering something from the UKOnline Pc storeslike this prebuilt

And grab a video card like a GT240 which runs on a 300w psu fine. to get you started.
