Out of that build I like the RAM, CPU, Case and OS (if you can get it cheap or need it). The mobo is fine as long as you don't overclock as it uses a foxconn socket that can damage CPUs, not necessarily fatally tho.
For the same price you can get a fast 500GB harddrive: http://www.ebuyer.com/product/158860 http://www.ebuyer.com/product/146252
The GPU is only fine at low resolutions, otherwise it is not the ideal gaming card.
The PSU is not from a company that I know anything about, so therefore do not trust. It is unlikely that it could deliver it's rated wattage at all or at least not for very long. The PSU is in many ways the most important part of a system, as a bad one can cause damage to the other components, so I think it is better to know that you have a good one.
If you fill out the format from here it would be a bit easier to help you in specific terms: http://www.tomshardware.co.uk/forum/261222-13-build-adv...
I will say that if you don't want to spend much more money overall, then I would suggest changing the CPU to a Phenom II X4 955, suitable mobo. And then up the PSU and GPU from those savings.
