I did a mix of Aria and eBuyer because some parts were cheaper/not available from just 1 of them.
CPU: £87.59 AMD Phenom II X4 965 BE
£99.23 MSI 890GXM-G65.
RAM: £40.10 8GB G.Skill Ripjaws X 1600 CAS9
HDD: £42.22 500GB WD Caviar Black 7200RPM
GPU: £119.99 XFX HD 6850
£66.91 Corsair TX650 V2.
OS: £75 Windows 7 Home Premium 64-Bit OEM
Total = £531.04 inc. VAT, not sure about shipping cost.
Couple thoughts I had while doing this:
1) Are you reusing the optical drive already in your case? I assumed so and left one out.
2) Couldn't find the internal dimensions on your case, check them against the ones for the TX650 I posted to make sure it will fit in your case.
2a) Check the dimensions of the GPU to make sure it will fit in your case.
3) May want to price compare with other shops to make sure you're getting the best deal, suggest these specific parts though.
4) Left room in the budget for a dual tuner card, not sure whats good/bad so its up to you to find it.
*Edit - Free time + boredom = looking at other online retailers for you.
Checked against: Scan, Dabs, Misco, Novatech, Microdirect, and Overclockers UK.

Any other parts that were less expensive it was a negligible difference (<£1).
