All I'm going to say is that if you don't put pics in this thread or the "trading stations" thread I'm never replying to your PMs again 
Really cool that you pulled the trigger. You'll LOVE those six-core 5600 Xeon CPUs. Even at lower clock the things are so robust its literally adding an extra quad-core CPU to your machine. You have more than 3x what the average trader has in their desktop between L2 cache, RAM, HDD/SSD and the benefit of hyperthreadding.
That's it - you won't hear another word from me without pics of 12-mon setup!
Yes, sir.
With the help of many people on ET, I was actually all set to go with following i-7 Desktop Configuration but was really nervous because I have never built a system. Then you guys came to rescue & suggested to try Dell Precision workstation with 21 day free trial & you WinstonTJ cleared up the confusion of 4 PCIe x16 slots as well as building a finest & extremely powerful Precision machine from barebone for almost half the price which opened up future possibilty of building such trading machines rather than buying from Dell & I am very grateful to all of you. You guys are the best.
I still have lots of work to do to build a desk for 12 monitors & will need your help & I am starting a separate thread for it so please give me your suggestions & again many thanks in advance for helping me build a suitable desk too.
