Before I blow the green...

I have been looking, thinking, reading for a very long time now. (I always plan my big purchases) I have this in my shopping cart about to checkout. Are there any changes that should be made before I spend the money.
Case: Lian Li PC-V1000B
http://www.newegg.com/Product/Product.asp?Item=N82E16811112072
Are there issues with PSU's fitting?

Mobo: DFI LANPARTY Ultra-D nF4
http://www.newegg.com/Product/Product.asp?Item=N82E16813136152
Heard lot of mixed things about this board. Hopefully I won't have much trouble with it. Seems like one of the best boards available.

PSU: 520W PowerStream
http://www.newegg.com/Product/Product.asp?Item=N82E16817104152
by the way? what is this ones difference? exact same?
http://www.newegg.com/Product/Product.asp?Item=N82E16817711002 (its 20 bucks left after a mail in rebate)
Is there a Mobo/PSU/Case malfunction probably going to be happening here? Fitting in the case? Killing the PSU or mobo from the pair of them?

Processor: AMD 64 X2 4400+
http://www.newegg.com/Product/Product.asp?Item=N82E16819103546
Seems like king choice to me. Definitly future proof and hopefully the 1mb of cache will help me in later gaming more then it does currently.
Is it hard to get this mobo set up with proper drivers with the mobo, or anything else? I hear im going to be having to do some bios flashing and driver finding and such for everything to run smoothly? I HATE random crashes and errors

CPU Heatsink: Thermalright XP-120
http://www.newegg.com/Product/Product.asp?Item=N82E16835109118
This is the one I want for my baby 4400? Weight is not a issue or anything else is it?

CPU Heatsink Fan: 120mm Panasonic Panaflow
http://www.newegg.com/Product/Product.asp?Item=N82E16835180087
Best choice for the XP-120 if it ends up that way? There is also another option for a 120mm panaflow but it seems to run faster but will be louder. I have a goal of keeping my system pretty quiet.

Video Card: eVGA 7800GTX PCi-Express
http://www.newegg.com/Product/Product.asp?Item=N82E16814130248
Best video card available to buy if you ask me, I also hold the option a year or two down the road to upgrade mobo and get a second in SLi. Hopefully prices will be cheaper then. Thats a big mabey. I hear this card barly fits on the Ultra-D any comments?

Video Card Cooler: Zalman ZF700
http://www.newegg.com/Product/Product.asp?Item=N82E16835118117
Best air aftermarket cooling I think you can get, seems good price and will allow for some overclocking.

Memory: Crucial Ballistix 2GB (1GB x 2) DDR 500 (PC 4000)
http://www.newegg.com/Product/Product.asp?Item=N82E16820146578
Sounds like the best memory money can buy. Should let me unleash anything I can get out of my 4400. Will not cause any bottlenecking of any sort, runs the best as far as im concerned.

Harddrive: 74GB WD Raptor
http://www.newegg.com/Product/Product.asp?Item=N82E16822144160
Looks good for gaming, my other computer had one, seemed to be great. Would put O/S and Games on it.

250GB Maxtor Maxline III
http://www.newegg.com/Product/Product.asp?Item=N82E16822144185
nice 16mb cache, for storage and media.
However Im still in a HDD perdicament. Do I want 2 Raptors in Raid? 2 Maxtors seperate? 2 Maxtors in Raid? With gaming in mind, and a need for storage/media what are my best options?

Sound Card: Creative X-Fi
http://www.newegg.com/Product/Product.asp?Item=N82E16829102188
Hear a lot of good things about these, it will be my first time i've ever used anything non-onboard sound. Still a little skeptical about this guy.

Keyboard: MSFT Standard PS/2
http://www.newegg.com/Product/Product.asp?Item=N82E16823109125
Seems to be what I like, cant complain.

Mouse: Razer Copperhead
http://www.newegg.com/Product/Product.asp?Item=N82E16826153105
or
Logitech G5 Laser
http://www.newegg.com/Product/Product.asp?Item=N82E16826104191
Never used anything like either of them, but I need a gaming mouse and I would use it for desktop purposes as well as gaming. I've adapted to such ways. Still not sure, mabey something can swing me in a direction.

Mousepad: fUnc Black Mousepad
http://www.newegg.com/Product/Product.asp?Item=N82E16817114301
Never used anything like it either, not too sure.. but i need quality mousepad for my quality hardware and equipment.

What do you guys think? Anything before I blow the green!? I asked a few questions, mabey you guys can be of some help
PS: If I do decide watercooling, Ide buy the Swifttech H20-Apex Heavy duty kit and buy something like a maze 4 waterblock for the 7800GTX.

Thanks,

Build a second one for me!

Seriously, that looks like a killer rig.

Make that three, I could use another comp
Looks good

seeing as how nobody answered your questions, the second psu is better cause it has one rail instead of two. I would hold off on the Zalman VF700cu cooler cause stock can oc pretty well and just get a stasis thermal later down the road. Otherwise everything is good.

I used several "good" mousepads, and I like the XTrac Hybrid a lot better. There are better heatsinks that you could get too, but the XP-120 isn't really a bad choice.
