Well, I think it's time to replace the old AMD K6/2 500 running on a Tekram P5MVP-B4.

I'm after any comments/suggestions on my proposed new system, with the following specs:
ASUS A7V-E mainboard
AMD Athlon 1GHz
256MB PC133 SDRAM
Philips 24x CD-ROM
Acer 8x4x32 CD-R
GeForce MX2 Video

I still need to decide on a case. I believe the Athlon CPUs are pretty power hungry, and I want to leave room for adding an extra HDD or 2 in the future. Will a 250W be ok, or should I go for a 300W?

Also, since I haven't used this configuration before, are there any known issues with the GeForce MX2 and VIA KT133 mainboard chipset?
