First attempt to build my own PC (Help please)

Hello Everyone!

I am planning on building my own computer after a horrible string of PC's from dell. I am a bit timid in attempting to build my own, as if anything goes wrong I wont have more money to buy additional components. I am looking at $1,000-1500 price range for components, excluding the monitor. I will have additional money to spend on a 22-24" Monitor. The only thing I really know, is the case I would like:

Would anyone with much experience, be so kind to suggest a build within my price range? I will be using this computer for gaming (WoW, EQ2, WAR maybe..) and graphic design, in addition to the general use. I would be very greatful for any help.

Thank you!

I should have added that if you don't intend to Overclock (from your post it looks like no) The Q9550 at $325 might be a better option for you.

alternative graphic card HD4870 $260 although i'm a bit hesitant about crossfiring 2 4870s with a 610w power supply and 8x/8x socket.

I appreciate your help dirtmountain! I know a little bit about various components and have opened up and moved around video cards and ram. Aside from that, I have never attempted to build one. It was suggested I do so in several forums I have visited inquiring about a new PC. I have grown frustrated with ordering computers from Dell, and other companies, so Im throwing caution to the wind. I have a co-worker who has built systems himself, and I may get his assistance to assure I dont make any fatal mistakes.

I definatley think I want to go with the Q9550. I also think I want to spend a little more money in other components to add to what you had suggested. Here are some items I have set aside at Newegg:

This case looks good (least I think so) and it looks like it could keep things cool. Your thoughts?

The Q9550 CPU looks like ill go with that.

This Motherboard has received several good reviews and I was curious what you all think of it?

I was wondering if this would be a good choice for SLI / Crossfire? (should I go that route)

I have also selected the DVD Burner you had suggested for my optical drive.

Also, I am interested in crossfire with the HD4870 cards you had suggested. Do they match the above mentioned MB well enough, and is there a bridge I would have to buy seperate to crossfire? (sorry I am a newbie)

I also selected this corsair ram and was wondering your opinion on it?

I also was considering this harddrive and was wondering if it would be a waste of money or worth it?

Due to being involved with graphic design and gaming, would the speed difference enhance those programs and games, or is it not worth the money?

This has all added up to about $1800. Its over the selected range I had originally offered, but it is doable for me. I may have a 22" LCD monitor to use rather than purchasing a new one. If thats the case, then 1800-2000 would be sufficient for components.
