£1000 First-Time Build, Last Minute Checks

Basically, I'm building a first-time gaming PC, with a budget of around £1000.
I'm a complete rookie at this sort of thing, and getting this far has taken a lot of research and time!

But, as a complete beginner, I don't actually know whether the components I've found will work together. Or if they'll even fit in my case!
So, if anyone would possibly be kind enough to tell me if this will work as a PC, or if I'm missing anything, I would be really grateful!

Also, if you have any idea of how I could save money without compromising in performance, I'd be pleased to hear your suggestions!

Thanks in advance!


Approximate Purchase Date: This week!

Budget Range: Around £1000

System Usage from Most to Least Important: Gaming. Then surfing the internet or watching films if I have spare time

Are you buying a monitor: Yes

Do you need to buy OS: Can probably get 64bit 7 for very cheap/free

Preferred Website for Parts: eBuyer.com or anywhere else that'll end up cheaper!

Location: East of England

Parts Preferences: Basically the brands I've listed

Overclocking: Not at first

SLI or Crossfire: In the future

Your Monitor Resolution: probably 1920x1080

Additional Comments: I'm not particularly fussy about much, I'd just like to get the best performance for my money

And Most Importantly, Why Are You Upgrading: I want to be able to play my Steam library, and new PC games for a few years to come! (Day Z is a must)
