A forum is practically built to argue. I wouldn't consider it a flame though, we just simply disagree. If it was a flame thread, it would've been closed by now.
People have some suggestions, others have better ones. I make mistakes, but I do admit to them. But Hacp immature act of rubbing it in is very unnecessary, and I find it very difficult to talk with someone like so. You wanted an EXTREMELY OC'able computer, and he simply doesn't understand that that is impossible with a low budget. Anyone would agree. 200mhz is hardly an EXTREME OC. Low budget can't afford adequate cooling, decreasing the ability to OC very high.
Hopefully that is a done deal as I'm sick of dealing with people like so and I'm sure your sick of people corrupting your thread. I apologize for doing so, just got caught up in the moment.
After rambling on a bit, now for your build.
I think damasta55r hit the spot there. You would probably be able to go with some cheaper RAM if you want to save, but since you want to OC, good RAM will always help.
Between the two PSUs, the Rosewill seems to be a very good "bang-for-the-buck" PSU. It certainly isn't a name-brand PSU, but from what I have heard, it will do your system just fine. I would consider getting a better PSU in the future if you plan to OC. You may find yourself having to pump out more voltage, and you certainly don't want to take power from something that will crap out.
For the GPU, would Leadtek be a better choice? I can't stop seeing so many people with Leadteks for the 6600GTs.
That build has the best DVD burner out on the market, NEC 3540a. A DVD burner is a DVD burner, but you will only buy one and keep it through upgrades.
You could probably get away with some OC straight out of the box. I would definitely consider getting an aftermarket heatsink until you can save up money for a serious cooling system (if you plan to). Look into the Thermalright XP-90
or that Zalman
. It will most definitely increase your ability to OC for a very small price. Well worth the bucks.
