This was fun to do.
I did go a little crazy with the harddrive set up. But hey, with 8TB of storage (or you could go with 4TB in a RAID 0+1 array), you're not going to run out any time soon. And if you're not comfortable with doing a RAID 0 for your OS drive(s), then just get the
Vertex 2 120GB instead.
Also, about cooling:
If you're going to overclock, get the
Prolimatech Megahalems with a
Gentle Typhoon that matches how much sound you want it to make.
I will admit, reflex's build is the better performer. But his is a good chunk more, and that extra performance would only be noticed in benchmarks. They would perform the same in every game (minus Metro 2033 @ max @ 2560x1600). Mine also uses quiet a bit less power.
Both would be good computers, no doubt. His is slightly better in performance, and has more bells and whistles, but also costs a lot more. It's your decision.
