Ok so first i want to reply to your post.
The reason that we want to "do-it-yourself" is because, without even looking at the mobo provided or the ram i can tell you that those video cards are nothing compared to the one you can put in your "custom" build... for at least $100 less in total cost.
...ok i stopped and looked at those builds... that case i showed you earlier... the one you like alot... may make the fans louder because of the conflicting fan directions... and it looks like it could work but that fan on the clear side panel would have to be set as an exhaust, otherwise... the cpu fan... and rear exhaust fan are going to cause a stronger air flow and all the cool air sucked in by the side fan (as an intake) would mostly just get sucked right back out by the rear fan. haha... at least it looks like that to me. that side fan would have been better off at the bottom.
anyway here's my build... is a lil more than the last one, but the RAM i chose for the last one was saving us alot of cash... shipping/MIR/discount...

after MIR($80) $891.96
So that leaves room to slowly upgrade... Water Cooler, Better/More RAM, 2nd GPU... wutever you plz! That leaves me kinda ****ed, cuz i thought i could do it for cheaper, but thats still not bad for a i7 build that will run almost any game you got at max lvls on 22" and under... iono about over haha! I'm sure it would still kick some A$$
P.S. if you want to change anything, it may add more to the price than just the paying price difference, because i strategically chose most of the products for either free shipping or MIR, but i still tried to use the better/more reliable brands at the lowest cost. Let me know what you think about the build... if you can cut cost anymore please share.
