I don't have too many complaints, for a first go it's not bad. This is for gaming, correct?
1. You've got an overclocking motherboard (Z87 as opposed to B85 or H87 - AFAIK it'll still function but motherboards are ostensibly the same for non-OC purposes and you may as well save the cash), a processor that can't be overclocked (4670 as opposed to 4670
K) and a CPU fan that you don't really need unless you're overclocking. Either flip the processor if you want to overclock, or change the mobo and dump the Hyper 212. Stock cooler should be fine unless you're going for something really really quiet.
2. I'd argue that you don't really need more than an i5 4570. It's about 5% worse, won't be a bottleneck in games and it's another £15 or so off the bill. If money isn't really a problem then absolutely fire on the 4670.
3. No idea what Palit are like for GFX cards, though with nvidia it's hard to go wrong these days as every card has to meet their minimum spec regarding reliability and performance. The 770 ASUS DCUII and MSI Twin Frozr are basically the same price on Amazon, and they tend to be on the good side of things.
4. SSD: the go-to recommendation is a Samsung 840 Evo and the 120GB is only a quid more than the one you picked. Again, not even sure if it's a bad choice, I'm just changing stuff where there's basically no price difference to something tried and tested. This is where I'd use the cash you saved above and stretch for a 250gb - performance and lifespan increase with capacity, to the point where a 250 should never break before the computer is completely obsolete. Note that SSDs perform significantly better when they have at least 20% capacity free.
5. HDD is fine but you may as well save £4 -
