Help with New Spec ?

[Yarrum]

Hi, decided to finally upgrade my 3 year old system which has the following.
AMD 3000
Radeon X800
1 Gig Ram
200 gig IDE Hard Drive
Antec P160 Case
Samsung 19" Monitor
XP

The only thing I will be keeping is the monitor and I will pick up a mouse/keyboard/speakers no problem.
I'm looking for a decent spec machine which will run Vista in all it's glory, surf the net and play the odd game or two. Not fussy for any overclocking but it would be a bonus if it run quiet.

I have a budget of around £700, any help would be great.

Thanks

Thanks, I have placed this spec together, does it look ok ? I presume everything would be compatable. Would I also require extra cooling bearing in mind I will not be overclocking at this time.

Thanks again.
