If you want to be able to overclock, yourself, you need to change to one of the Z77 motherboards. The LK also gives you the advantage to be able to add second card in crossfire, if that is likely.
Case is their own make, so probably OK, just don't know it.
I'm not a great lover of OCZ, for power supplies. Much prefer Corsair.
The Asus monitor is OK, but the Dell Ultrasharp is a lot better. You don't have to get it from Chillblast. If you shop around, you can get it for around £240. Well worth the extra, if you can afford it.
