hi, i need a general propose pc because my gaming pc consumes too much power and i using it to watch movies a lot lately, so i need a budget pc for watching movies, web browsing and office work i need it to be cheap as possible budget is around 200 pounds. not inc monitor, mouse, keyboard. maybe a bit of photoshoping
Same route i went down. Main powerful pc for gaming only and a basic pc for everything else. My gaming pc draws 242w while gaming and my second pc draws 89w idle/ 112w load.

I built mine for less than £150 by getting most of it off the bay. It's still a decent spec though.
Biostar P35 mobo - Brand new £35.
E4300 cpu - Left over from an old build.
2Gb Patriot Extreme PC2 6400 - £17
Seagate 7200.10 320Gb sata hdd - £26 Brand new.
Samsung 20x Dual Layer DVDRW - £15. Brand new.
AC Freezer 7 Pro - £11 brand new.
XP Pro - £27.50 - Brand new and sealed.

Antec NSK 4480 case - Free. Local pc shop had a pile of cases from peoples upgrades that they were going to dump so i asked if i could have one and they said help yourself.

Winpower 550w psu - Free, Out of a case that i built a pc for someone. They wanted a better one. Yes it's a Winpower but it's been going strong for over 2 years now. It is getting replaced by a modular one soon though.
Cracking little rig and will even clock to 3.4Ghz if needed.
I will do you a spec from here after i have had my dinner but second hand bits would be the way to go.
