Which OS should i install on...

k i got an old Dell C521

Specs are;

RAM: It's gonna be 1.5GB i think as i'm gonna take out 3GB of it and stick .5 GB in :P
Hard disk: 150GB
CPU: AMD Dual core 5200+
GFX: NVIDIA GeForce 6150LE (not that it matters)

And i want to install an OS but don't know which on it..

Basically its gotta host like COD4 server, vent/TS n stuffz.

Suggest plx

Youll want better specs for COD4 depending on the amount of players its gotta host.

I would go for CentOS if its linux server based (COD4).

WEll cod4 ran fine on a laptop with 200mb ram :P no lag etc ;)

its mainly the upload/download speed on your internet that is the real killer.
