I am wondering what should I set as a starting price on a combo I have that is getting removed from service next week? Specs are as follows

Asus A8n-SLi Premium
Athlon 64 x2 4200+
2x 1gb Crucial pc3200
2x 512 mb Crucial pc3200
for a total of 3gb of mem
Also have the drivers and such I downloaded on cd also I have the SLi bridge, i/o plate and a few if not all of the original cables that will go with it. Also comes with a Soundblaster Audigy 2 sound card and breakout box.
