Is this a good Build?

Hey there, I got the parts together for my friends new PC and I'm just wanting to check if this PC is worth its money or if there anything I can replace a part with that would be better and cheaper:

Corsair Vengeance Ram 4gb x 2
Asus DVD-RW Drive
Corsair Carbide Series 300R case
Corsair Builder Series CXM 750W Modular 80 PLUS Bronze
MSI Z87-G45-GAMING ATX Motherboard (Intel Z87)
Asus GTX 770 Nvidia GeForce
Intel Core i5 4670K

I just want expert advice to make sure im not doing any stupid mistakes and that everything works well together.

The total price is £750 ish for all those components, is there like any improvements I could do to make it stronger and cheaper?

Probably could change the PSU to something of higher quality like a XFX 650w bronze, it'll still be more than enough for your system.

Another thing you could do is to change the mobo + cpu combo to a i5 4690k + Asrock z97 extreme4 if the price approximately the same or not too much more.

Yeah I did actually suggest mention the processor and mobo to him but he said he'd prefer to keep it under 750 max.
