Nowadays you don't need the SLI bridge anymore but a lot still do it. I received one with my GPU but I've never received one with my motherboard but you can always buy them seperately.
Also, what resolution will you be playing at? the 760 only has a 256bit interface. When it comes to running cards in SLI, it's better to have 3GB/4GB of VRAM as the two GPUs will share the 2GB between them and not combine them.
Wootware is currently having a special on the
PowerColor AX7950 3GB GPU for R3 499. This might be a better option as the higher VRAM will benefit you in the future. You can see
here that the 7950 and 760 are extremely close in performance.
With the motherboard, it's an ATX board which is the standard nowadays so there are much cheaper options than that Thermaltake case but a case is also preference so we'll leave that alone.
I would recommend getting a 'K' CPU as running a CPU at stock on that build will bottleneck the system a lot. You would want to OC to at least 4.5GHz to prevent any sort of bottleneck happening. Something like the
i5 4670k and then get yourself a decent CPU cooler. Maybe some like
this?. I've got that on my CPU and my temps idle at 28*C and I'm OCed at 4.5GHz.
As recommended earlier, an SSD would also highly benefit this build if you don't already have one. If you want to use the 4TB as your boot drive, expect boot times to be slow and games to take a while to load up. I made that mistake before and immediately changed it.
Hope this helps.
