I can't help but comment on the 1 , couldn't they cut the price to $9000
Sorry its out of my budget i'm only allowed to spend $9000 not a dollar more. QQ
Few things:
4x 6GB GTX TITANdoes not mean you get 4x the performance and 4x6GB VRAM. You'll still have the same amount of VRAM (6GB) and have about 90% more performance than 1x GTX TITAN (30% per card).

Also, for cooling, it would have been a lot better if we went custom water loop. I would have done a 4x WD RED SAS drives instead of Seagate. Or 8x 512GB RAID 0 drives or something ridiculous like that.

Also, he's not using any fans on the thing, and he could get a better PSU.

As for screen, I would get dual 4K screens with a RAT 7 and a Ducky Shine keyboard.

THAT's the best you can get :D
This thing is crazy... but I think that it's too expensive for what you get, still if I had the money I would totally buy it.
