Work in progress!
UPDATE [29 October 2013]
I am going to scrap the idea of the G.Skill Ares memory as I can purchase the Crucial Ballistix Tracer memory for £10 cheaper (£55 vs £65) and they are CL8 verses CL9 (so tighter memory timings) and they have the awesome customization software for the LED lighting effects. Even though the LEDs won't be visible from the exterior I think just knowing they are in there is satisfying :)
The memory also has nice black heat spreaders and PCB which will go great with the overall internal design and choices. Tiny details make a big difference in my opinion which attracts me big time as being a tech lover and gamer.

I am also going to swap the 600w PSU for a 500w because I figured the box will use less than 600 and it's pointless spending the extra.
