Question about PC :)

Hi,
I am interesting is it possible to set up server with my PC :

Quad Core 2.66 GHz
RAM : 4 GB
nVidea GeForce 9600

and internet :
Download speed 2 mb/s, upload speed about 350-500 kb/s

With this staff could I open Kal Online server with online ~30-50 ppl? :)

Should work. I had once a server with 20 people and 30 kb/s upload. Was a bit laggy but better than int xD. Also I had a single core and I think only 1 GB ram...( it was 2006).
