I want to build a small system for LAN parties and wonder if this system could handle the reqs for BF1942

With the onboard video, no. But with any capable AGP card in it, the system rocks for LANs. Mine has now been to Quakecon, SPLAT twice, and has been moved to a few friends houses quite a bit. This weekend it's going to EverLAN. And it works perfectly with BF1942. The front USB and headphone jacks are useful for sound and the joystick I use for the airplanes.

My box has: P4 2.26, Radeon 9700, 120gb drive, 512 DDR 333 memory, and a Plextor combo DVD/CD-RW drive.
