Any Suggestions for what i should get for the power supply and case? I'm not too sure if I'm missing a component on this list
I play a lot of games... WoW, Css, CoD4, maplestory, starcraft, warcraft, and in the future, Warhammer Online
Does this all work together so far?
If you don't think i should have something up there just tell me
Does anyone know of a cheaper monitor that will get the job done for gaming?
So for the price is up to 800 dollars.. I'd like to keep it under 1000 but if I must go over then it's fine.
This is my first time building a custom computer after 2 years of having a million problems with my CyberPower built computer

3650 is not good enough for most new games. Get at least a 3850, ideally 3870, 9600gt, or better. Get at least a 450 watt psu with good 12v rail ratings. Get a cheap midtower case with good airflow. CDROM is cheap, a dvd writer cost only $20-40. Not sure about motherboard, as I'm not familiar with amd chipsets. X2 5600 is a decent budget cpu, if you can get it cheap.

Thank you for your input
I've decided on the Antec 900 case
Does anyone know if this is a good motherboard or how about the  
ABIT Fatal1ty AN9 32X AM2 NVIDIA nForce 590 SLI MCP/SPP 190 ATX AMD Motherboard
 
What about sounds cards and networking cards. Do I need to buy those?

Graphics card... 3850 is good.
 
RAM... good enough.
Hard Drive... why would you buy a 1TB hard drive for a sub-$1k build? If you need more space you can upgrade, but a 500GB would be plenty for anyone. I have tons of games, music, video, and several operating systems and stuff, and I only have 280GB of space, and don't need any more for the time being. I would just get a 500GB for now, and if you need extra hard drive space, so be it, get another one, but there really is no point to getting 1TB now.... oh, I forgot about this drive: http://www.newegg.com/Product/Prod [...] 6822136218
This drive is fast, cheap, and has plenty of space, definately go for that.
 
Processor... good processor! Not good for overclocking, but thats ok. It was actually the processor that I was going to upgrade to.
 
I do not recommend getting an ECS board! Yes they sometimes have good features, and yes they are dirt cheap, but if you read reviews that are [B]from people who have used the board for over a year[/B] many times, the boards burn out! They are cheap for a reason!! http://www.newegg.com/Product/Prod [...] 6813128075
Get that one for sure. That was the board I was going to get for my new rig. Getting an AM2+ board over an AM2 board is a lot safer. They are better all around.
 
That OCZ power supply is an OK power supply. Not great, but OK. If I were you, I would not skimp on the power supply, especially because if it fails it can destroy your system! Get this one: http://www.newegg.com/Product/Prod [...] 6817139005 Along side of PC Power and Cooling, Corsair probably makes some of the best power supplies out there.
 
I speak from experience, sir. I bought a 19" monitor early on (and have a 20" on another computer) and regret not spending the extra cash for a 22". Get the Acer 22"! It's way cheap, and is definately worth it. http://www.newegg.com/Product/Prod [...] 6824009094
 
Good luck on your first build.

Thank you very much.  
I really appreciate it.
 
So what about sound cards and networking cards?

Generally, the only card you really need to buy is a graphics card. 99.9% of the motherboards out there now have built in sound cards and ethernet (networking) cards. Built in audio used to be crap, but now the built in audio cards are much better, and for a sub $1000 builder, it is definitely suffice. That particular motherboard that I posted above has excellent onboard audio, too. Realteks ALC88x is generally the most common audio for motherboards, though others exist.  ALC883 onboard is average (pretty standard, I have it in my current board from 2006), ALC888 is pretty good (its what my new board has) and ALC889A, which the Gigabyte one has is great. Even ALC883 is still good sound. I have it paired with some really nice headphones, and it sounds amazing. I'm interested to see if the step up to ALC888 will make a difference.
 
Bottom Line: You will not need to buy a separate networking or sound card!
 
Oh, and I meant to say that the AM2+ motherboard was safer for upgrades in the future, more so then an AM2 motherboard.

Integrated sound in your mobo should be plenty.  As for networking, the mobo has ethernet connections so if your directly connected your good.  If you want wireless, and most mobo don't have wireless built in, you need to get a pci or usb wireless card/adapter(http://www.newegg.com/Product/Prod [...] 6833315041)

Thanks so much guys I think I have my final build here.
If theres any last suggestions at all just lay em down.
I can't wait to have my first custom computer
