A few things to mention here.
The case you chose is a mid tower, not a full ATX. This means you cannot use the large graphics cards like the Radeon 5870 or higher. Well, you may be able to use one if you remove the hard drive cage and move some things around, but using Crossfire in a mid-ATX is not suggested given the thermal issues and space within the case.
The motherboard is okay, but don't think you're future-proofing yourself very much by spending the extra cash. The board doesn't take USB 3.0, you would get better audio using a dedicated card like the Xonar D2X
, and most of the technology is shared with all 790 chipsets. However, the 790FX does have a few things over the 790GX. First, it has a better audio system, but you would get much better results with a drop-in card anyway. Second, it has dual PCI-Express x16 slots which both run at x16 while populated in Crossfire, whereas the 790GX two PCI-E X16 slots where one runs at X16 and the other at X8. This is only a factor if you use CrossfireX at all. All AM3 boards will be able to use any AM3 CPU that AMD produces, so long as there is a BIOS for it. This includes new six and eight core CPU's, which no application can even use, yet. You can save some money with the 790FX board by getting the GIGABYTE GA-MA790FXT-UD5P AM3 DDR3 AMD 790FX ATX AMD Motherboard
instead of the Asus.
As for the PSU, modular units are helpful in keeping the cables to a minimum. However, you can simply use tie-backs to keep the extra cables out of the way and you will lose some wattage due to the modular nature of the Zalman. Quality modular PSU's will also cost a bit more. The wattage for the PSU is determined largely by a graphics card, or cards. Two 5770's require 600W, factor in an extra 100W margin and you would need 700W. If you go for the 58xx series, you would need about the same. I didn't even know Zalman made PSU's so I cannot be sure of their reputation. Corsair, however, I've heard many good things about and use in one of my PC's. If you want a modular unit from a company I've heard of and use, you can try the SILVERSTONE ST85F 850W ATX
. Very few people need 1KW PSU's, those that do, usually have multiple HDD's, three or more, and several high-end, power hungry graphics cards all on an extremely overclocked system.
The RAM is fine, but you will be paying more for the 4 x 2GB Kingston kit than you would simply buying two 2 x 2GB Corsair kits. If the RAM already comes OC'd, the motherboard should set itself to the proper speed automatically with 1600 being as fast as you can go with the RAM. You won't take that big of a hit with 1333 memory, it's still plenty fast.
I don't go for the super fast HDD's, since I look more for storage capacity and cache than how fast the platters spin. There are some slight performance differences between 7500RPM and a 10K, but in actual usage, you may not be able to tell that much. For extreme speeds, you could always get a SSD, but that would blow your budget to pieces. Also, I suggest avoiding RAID for all home systems. RAID should be used for redundency and can be helpful in mission critical operations but it can lead to headaches if not setup properly. If one drive in a RAID 0 setup fails...
That Zalman fan you linked to may be a 120mm fan, I cannot find any information on size at Zalman's site, but with a height of 125mm, I assume it is. Mid ATX towers have problems with large fans in that category. Usually, 92mm fans are used in those cases. A good 92mm fan I use in my old 939 AMD system is the ARCTIC COOLING Freezer 7 Pro Rev.2 92mm Fluid Dynamic CPU Cooler
. Well, actually, this is an updated version of that original Freezer 7.
Both CPU's are unlocked and are the same. However, the 965 operates at 140W. If you feel confident enough to overclock the 955, go ahead and save cash. All overclocking should be done in the BIOS.
