Media center PC?

Motherboard: p5mvp3-at
CPU: AMD-K62 400Mhz
IDE: ATA/33
AGP: Nvidia GeForce MX 4000
RAM: 640MB SDRAM
2xUSB 1.0 onboard

Bought it at a garage sale for $10.  But it had a Voodoo3D AGP card in it, I replaced it with the above card (works).  This is a very strange motherboard.  Takes either AT or ATX power connectors, has ISA, PCI, and AGP slots and according to the manual I can install either a AMD or Intel CPU in it.

Anyway, think I can use it as a media center PC, mostly playing stuff off the network?

What kind of video do you think that old CPU can handle? The AMD K6-2 has miserable floating-point performance to begin with, and it's only 400 MHz.
