What do you think of my first gaming pc setup?

I have decided for the last year now that I would like to build a gaming pc. It is my birthday soon and I'm going to ask for money and hopefully get £200. I already have a laptop with all the proccessing power but rubbish intel integrated graphics. What do you think if I built a pc with these parts (Link Below). I will use it purely for gaming and games like Minecraft.

Added (1). I have upgraded it with a better graphics card with a lower voltage power supply and I have removed the case so I can get a cheaper one separately. Http://uk.pcpartpicker.com/p/2KZHl

With £200 your rig will run minecaft fine but will struggle to get decent gaming performance with more demanding games.
You need to improve your power supply, ditch the modular design and go for a lower power maybe 400W ( the whole rig will only consume 168W) and get a better version such as this

You could save by only getting 4GB RAM this would be plenty and go for a cheaper case

I would then save for a better graphics card, maybe second hand off ebay if you can get someone to bid for you - I got a S/H Radeon HD 4890 for £25

5450 video card is fairly low end, you will not be able to play modern games (mid to high end) well at all. You need a better video card.
I also fear the PSU is not a true 630W one, with dual +12V rails. You should get a better name brand PSU, one with a single rail +12V design. It will cost more…

You can't build a reasonable (mid range) gaming machine for that money - double the money, and you can then start to consider it a "gaming" machine
