Where to buy a computer in Warsaw

One of the best places is open air computer market next to Metro "Pole Mokotowskie", Batorego street to be precise.
It's called " Warshawska Gelda Komputerowa"
this market is working only in the weekend, you can find everything computer related there, brand new and second hand stuff, motherboards, computers, laptops, monitors...etc.
the prices are very good there.
next place is a polish ebay like site called www.allegro.pl

I bought my computer in Saturn, in Arkadia shopping mall...
