Mini ITX budget spec

[InQ]

Looking to build a budget mini-ITX system for gaming on a 1080p monitor with only a ~250GB SSD required storage wise.

Games could be anything, mainly FPS though with older (CS:Source, CS:GO) stuff and will try some newer stuff (BF4 maybe, Evolve, Far Cry 4 etc).
Basically what do I need to push 1080p at high/ultra settings on the latest games and can it be done on my budget?

Budget is £550-£600 (not including OS)?
If I need to go extra to say £650-700 then I guess it might be do-able but it isn’t my default option especially if I can get the 1080p performance I require.

Cheers for that although looking at it i need a smaller case, like the look of the Silverstone SST-SG08B-Lite mini-ITX.
Picked the PSU as i know from some brief research it fits the case with a long GPU (has to be 140mm deep and not modular) plus added a 180mm case fan. Also added a right angle SSD cable as that seems to be recommended.
Otherwise generally fairly similar....do i need the Zalman multi connector you quoted, not sure what that's for?

OK well after all that i decided to have another look where i was putting the case and i've managed to relocate the Sky box to under the frame of the TV (its an LG with a kind of U shape stand) so that has freed up the entire level below in the TV stand (about 172mm tall).
So i'm now looking at a Silverstone GD10 and using an ATX....guess its gone off topic now so i'll post another similar spec in the Gen Hardware forum.
