Newegg has a guarunteed 30 day warranty, so long as there's no external damage, and most manufacturers have their own warranties on top of it. You can order them off Newegg, yes, but I suggest going to a shop, give them the list of parts, and asking if they can upgrade it/do better, because they shouldn't charge much to build and my computer is 170 less than you have to spend. On to the list:
Case: http://www.newegg.com/product/product.a ... 6811119077 (Don't really have to get this one, you can grab a sexier one, this is just the one I got.)
Video Card: http://www.newegg.com/product/product.a ... 6814130318
PSU: http://www.newegg.com/product/product.a ... 6817171018
CPU: http://www.newegg.com/product/product.a ... 6819103228 (Fastest dual core out there iirc)
Ram: http://www.newegg.com/product/product.a ... 6820211064
http://www.newegg.com/Product/Product.a ... 6820211066 (I got the RAM in that many sticks because my mobo supports dual channel)
HDD: http://www.newegg.com/product/product.a ... 6822148288 (500 gigs, you could get more.)
DVDR: http://www.newegg.com/product/product.a ... 6827106095
DVDRW: http://www.newegg.com/product/product.a ... 6827106245
EDIT:
Hur hur hur mobo: http://www.newegg.com/Product/Product.a ... 813130123R

If ALL of your RAM sticks aren't identical dual channel can go bananas.
OCZ with D9 chips or Corsairs pwnz00r regular RAMs.
Intel pwnz AMD in terms of performance.
AMD though is the bang for the buck experience if you don't want to overclock the system.
The 6400+ is basically a overclocked 6000+, so no need to spend on what you can do yourself.
GTS G92 is better than GT (and quite affordable to since I last checked)
For the HDD - just find one with uber huge ammounts of cache and buy two of them. RAID0 uuber fastness FTW.
And you didn't give a link for a MB or I missed it.

P.S. didn't read the whole topic so I probably epically phail.
EDIT: Gimme a budget ceiling and I'll try to compile something.

Red text makes you an idiot

Wasn't intended to be rude -___-
Whoops my bad....
OCZs with D9 are affordable. If CL doesn't make a difference you're a brick.
Intel is better in terms of performance, I am a TOTAL AMD patriot but I am not a stubborn jackass.
Intel's dual core processors provide a near100% of OC room.
Try to prove that the CPU has been clocked without uuber specialists who are payed 1k an hour.
GTS G92 is better than GT, the diference can be seen in, for example, Crysis.
Well, I'm probably so stupid I don't feel any pain (-__-')
For those who think that 1337 is a admitance of ♥♥♥♥ - RAID 0 on two 32mb cache hard drives beats the heck out of any loading screen out there.

And I kinda wouldn't call this phail...

P.S. Excuse me if I misspelled something - not native ^_^

Dual means two. So logically dual channel only works if all four sticks are the same. Gotcha. That's why it's color coded to indicate which two go with which. I ALWAYS WONDERED.
It really doesn't.
Intel and AMD are the same. I've dealt with both extensively and I have yet to see any difference.
Yes because overclocking means making your CPU the same exact speed.
You pay for the warranty ♥♥♥♥♥♥. If you want to go ahead and overclock from a 3.0 to a 3.2, be my gues and void your warranty.
There is no noticeable difference at all. None.
It seems so.
HD speed doesn't matter at all. If you're too impatient to wait for that HDD to give you your data, you're operating at a much slower speed of time than I am.

I kinda would.

CL counts if you clock.
The regular user won't see a difference, a benchmarking user however will.
Percentage when stated in relation to OC mostly refers to the ammount gained, therefore if you have a 1Ghz celeron and clock 10% you achieve a speed of 1.1Ghz....
Make them prove that you did in fact OC the given CPU.
There is a noticable difference, again for the benchmarker and slightly advanced user though (but there are minor differences for the layman too).
Hard drive speed doesn't really matter in everyday stuff, but in gaming it plays a small role.

Okay, you guys are starting to lose me a bit... But that aside, anything I need to know about the motherboard?

I know this is going to make me look bad but... Overclocking is altering a part to make it run faster, right? And if AMD would void the warranty I take it it's a bad thing. (Like I said, nearly no prior experience with computers)

So, now that we have the parts I should get, what else should I know? And how well will this run? What limitations would it have?

OC = raise the clock speed of your processor therefore gaining speed, heat and wear.
the first two are noticable, the last, if the computer isn't going used for centuries, not.

Motherboard should have expandability options - SLI, so that when the price drops, you can buy another gfx card and not be left with an aging system with no upgradability.

Nothing else comes in my mind at the moment.

EDIT: MSI fails in my eyes for some reason. For an AMD cpu me recomendz0rz Biostar, ASUS, DFI (suuugar) and Gigabyte. Gigabyte is THE microwave, but if you don't do extreme OC it works well.

I don't like the MSI brand for unknown reasons.
DFI definately leads the AMD motherboard industry (at least last time I checked aaand it was in my country with not the largest store supplies so I might be mistaken... :/)
I told that OC brings heat. -__-
The GFX card can be OC'ed too.
Benefits gained from usage of RAID 0 can be seen. -__-
If I typed 100% I mistiped, 70% is what i wanted to type.
Weell didn't know about that. I admit, owned.

You're a seem a bit too stressed about this....

Oh and stab me, punk

My I say, that's one hell of a computer! The motherboard is upgradeable, right?

And, what you put on the list is defiantly what I want? Would there by chance be anything better that has come out since you got your? (For the same price that is)

I just can't refuse to thrust my oppinions upon others.
Prove it -__-
And massive uuber game loading ^_^
If I wouldn't have seen it happen, I wouldn't say so -__-
Muah, actually it can, if you use "aftermarket" coolers The realistically achievable stuff is about 40%, but I just wanted to shine ^_^

Hope this post finally settles it... (",)

EVERYTHING in the PC is upgradeable, the only problem is that once you buy some things you really don't want to spend on them anymore.
CPU and motherboard are the two things you won't want to upgrade anytime soon so they haave to be chosen with care.

The PC won't run everything on high, but most games with reasonably programmed engines (not Crysis alike ) will run nicely @ high settings and with DX10 enabled.

Not rly. Mby except GTS G92

Like I said, take it to your local comp shop and see if they can come up with any better. I don't claim to know everything about computers, so it's possible I missed something. I just handed you my list, what you do with it is up to you.

ITT: Jesus christ you had best be done bickering, you two.
