NINE HUNDRED)(BLACK) ULIMATE FULL SIZE GAMER CASE
That's a nice PSU, but more than you need. For a single HD4850, 450W is enough. PC Power and Cooling, Antec, Seasonic, OCZ, and Corsair all make good ones.
For RAM, get DDR2-800 that will run at its advertised timings on the JEDEC standard 1.8V. Anything else is a factory overclock, which good DDR2-800 can reach anyway.
I'm going to disagree with jtt283 on the power supply issue.
750W is perfectly fine for what you're doing. Here's the reality. Your motherboard supports ATI Crossfire. If you go with the minimal 450W power supply, you will not have enough juice to add a second video card later if you choose.
Also, 450W might do for a 4850, but your next video card upgrade will want more power than that.
Not to mention, if you buy a GOOD power supply, you should be able to reuse it for a couple of rebuilds in the future. I'd rather spend a little more now, and keep the same power supply for two or three years than replace my power supply every time I upgrade anything else in my system.
As far as RAM. You really don't need more than 800Mhz (PC6400). But the 1066Mhz (PC8500) is getting cheaper all the time. If you don't mind the cost, there's nothing wrong with getting it, and then you don't have to OC it to push your system more.
Again though, 800Mhz is plenty for this current system. Future upgrades will find you with a new motherboard which will likely support DDR3 anyhow.

Since I get Asus P5E with 2x PCI 2.0 x16 slots which will run dual x16 for Xfire,and HD 4850,so I'm thinking to Xfire it within a year,therefore I choose 750W so that I won't change the PSU when I'm going to do Xfire.
JEDEC standard 1.8V
I'm sorry that I'm novice about this stuff.Can you explain it clearly to me,please?If OCZ said that the reaper compatible in 2.1V,what does it mean?Will my build able to withstand it?
Anything else is a factory overclock, which good DDR2-800 can reach anyway.
Does it mean OCZ Reaper that run for DDR2-1066 lose in the performance compare to DDR2-800 memory?I'm planning to overclock my E8400 to around 4.0 Ghz,so is OCZ Reaper good for overcloking?
Before I choose OCZ Reaper,I choose Mushkin HP2-6400 High Performance DDR2 SDRAM (5-4-4-12), 4GB Dual Pack,however I can't buy from online site since I don't have credit card and Mushkin HP2-6400 is currently out of stock in store,so I change to OCZ Reaper.
Everything looks good. There usually isnt hardly any price difference between 20" and 22" widescreen monitors so check those 22" monitors as well.
I will check for it.If the price is still in my budget,I will get 22" instead 20".Otherwise I will stick with 20".Thank you for you suggestions.
Instead of the Seagate 500GB HDD look for the WD 640GB AAKS or WD 640GB AALS models.
I don't want get too many storage since I still have 250GB external hard drive.After all,I get the seagate 500GB for $59.99CAD while it was on sale.WD 640GB AAKS cost $79.99CAD and WD 640GB AALS cost $94.99CAD which the price difference are $20CAD and $40CAD,so I will stick with 500GB seagate.Thank you for your suggestions.I'm really appreciate it
If you buy DDR2-1066 and then don't apply the factory-guaranteed OC settings, it will most likely run at DDR2-800 with 6-6-6-18 (or worse) timings.
I don't think you disagreed with me, jerreece, so much as made obvious my omissions. You listed some good reasons (and I'm sure there are others) for getting a bigger PSU than the minimum. Depending on future possibilities, get at LEAST 450W. For myself, I'm hoping there will be something like a 5670 that performs like a 4850 and needs no auxilliary power. I'm glad my furnace (and hot water heater) still need more juice than my PC.
