Advice for new PC

Hey guys, I'm planning to build a pc for the first time as my current one is pretty old. I've not built a pc myself before and I wanted to ask if what I'm planning to buy will work and is good enough for what I'm paying. I'm not completely computer illiterate but since its my first time I did want to check there are no glaring errors.

My budget is about £860.
The parts I've put down come to about £840 inc. vat+delivery.

The parts I'm planning to buy are:

I have a monitor, keyboard, speakers etc so I'm not buying parts that I don't need, but if you think there is anything missing please say so incase I don't have one and need to buy it.

Also I was wondering if it would be more efficient to buy two smaller harddrives and set them up together instead of one larger one? I don't know much about it myself.

P.S Since I live in England please don't suggest any non-uk suppliers

 

Yeah, and the links aren't working for me for some reason.
