1300-1500 Gaming computer... Advices needed

Hi..just saw your message...See if these help  
Few suggestions...

1. Case -
Both are very good cases...
NZXT if you want to break the code...
Another alternative for the case - CM 690...

2. Save some money on the mobo...Get the Gigabyte UD4P, has nearly all those features for less...

GIGABYTE GA-EX58-UD4P Core i7/ Intel X58/ DDR3/ CorssFireX & 3-Way SLI/ A&GbE/ ATX Motherboard

3. CPU - Nice

4. RAM - Nice

5. HDD- WD Black 1TB is faster and reliable but is about $20 more...though the F1 is not bad...

6. Dont waste money on factory overclocked graphic cards...you would get the o/c s/w bundled with most of the cards, that would allow for slight overclock in WIN itself...
So get the 1st option...

7. As for the monitor,
All those monitors are different from one another...
Sam Toc has inbuilt DTV tuner
Sam 23 has very high resolution - actually an odd one, and a GTX 275 would not be able to play all games with highest settings at that...
ASUS - Some what nice...

Get preferrably a 1080p resolution or 1920x1200 resolution monitor...
Other options...

8. OS - Vista has become better...
But save some money by going with WIN 7
they have valid licence till 2010 and they are as stable as Vista in the RC stage itself...

9. DVD - Always get a SATA drive...Thinner cable less clutter...

10. CPU Cooling -
For that price range, I would suggest TRUE

You have the right idea, but your build needs some fixing. The heat sinks, and motherboard you are looking at cost more money for no significant gains. In not so many words they are a "hose job". Take a look at this down below. It allows you to add another vid card for SLI later on. I didn't include a case in this build....that's your call. But if I was going to include one...it would definitely be the CM 690 which is going for $79.99 at newegg atm.

Christ gkay, you must have been posting your build while I was adding mine up.  

Thank u guys so much for taking the time looking over my post... im currently taking the advies from both of u guys and coming up with a new build soon... THANK U

@Why_Me  

I misssed out on the PSU totally...
+1 for Why_Me's suggestion...
That Corsair 750TX is suffice for 2x GTX 275 in SLI...
Get the 850TX if you are planning for tri-sli (But you wont need that much power for a 1920x1200 resolution monitor)...

You would only need a 1000W+ for running 2 GTX 295 in SLI...
