BF2S Forums How much could this sell for?

I need monies so I'm thinking of selling my current computer, so I want to know how much do you think I could sell it for in CDN/US currency.

Antec 900 +extra Antec 120mm fan for side panel
AsRock 775Dual-vsta (crappy board I know, But it was useful for upgrading slowly)
Intel Pentium D 930 3,0Ghz
2gb Corsair XMS2 PC2-5300  ( CM2X1024-5400C4 )
BFG 8600GT OC 256mb pcie
2X Western Digital 160gb SATAII (320gb total)
Audigy 2 ZS Platinum with front bay and remote
Turbo Aspire See Through Neon Light 500 Watt Power Supply
LG DVD burner


I'm also thinking of adding the following games to go with it;
Battlefield 2
Flight Simulator X
Silent Hunter III
Silent Hunter Wolves of the Pacific
Age of Empires III
Farcry


So how much could I sell this for with and without the games?
Karma for real help.
