Presetly its running off AMD sempron 2500+, a 20GB HDD quantum fireball

and a 17" CRT.
My parents would be using it so dont require anything fancy. Was thinking of building it around E2180 and onboard video. Created a separate thread coz people seem to have forgotten about onboard altogether.
Wont be requiring HDD and DVDRW as I already have both. Everything else required.
Please give me
options in LCD and PSU coz I believe they are going to be the most costly components, and I would like some cost cutting there if the budget doesnt permit.
Budget: as low as possible
