So this is my build so far.

I've been purchasing as I've had the money.

I've mixed ram brands which i hope isn't going to prove an issue. I was going to use a haswell i5 but the corsair xms3 voltage was too high for it to run at 1600mhz.

Hope evrything else is okay.

All feedback welcome!

I don't think you could physically mix ram, you could try if you want.

That motherboard will not support the power requirements for the processor. This motherboard is more expensive but it will support an 8 core CPU:

This is the one i had, dont know how the otherone got there

Well , any board with 760G chipset won't support an 8320, I'd recommend changing your CPU to an FX-6300 or change your form factor to ATX and get the board I linked. TBH I don't know why there are no matx boards that support the 8320

Oh okay. Thanks I'll look into that
