Eh, those are pounds, and 1 British pound = 1.9076 U.S. dollars. That's almost 2 dollars to every pound. Plus I'm not so sure they will ship to you (And if they do, I'm sure it will cost an arm and a leg). And, the power supply switch takes care of the voltage, a European Core 2 Duo = an American Core 2 Duo.
And, it will cost you more to buy from there. Their E6300 costs Â£144.99, which is $219.35. On newegg, an E6300 is $182.99.
See Wii. See Wii run. See Wii blow all the other consoles out of the water!
