New Build Opinion Request

Hello,

I am new to the boards but have been reading various posts for a about a week now. There are many people with very good questions and informative answers. This is why I am writing this post.

I have recently decided to build my next computer. I consider myself a fairly knowledgable person when it comes to computers and have been researching components. However, I still wanted those more knowledgable to provide opinions on the setup I have chosen. The following is the system I have chosen:

Case: CoolerMaster CM690
PSU: Antec True Power Trio TP3-550 ATX12V
MB: Asus M2N-SLI Deluxe AM2 NVidia nForce 570 SLI
CPU: AMD ATHLON 64 X2 5200+ (ADA5200CZBOX) RETAIL BOXED W/1MB X 2 CACHE 90NM 65W (WINDSOR)
RAM: CRUCIAL BALLISTIX BL2KIT12864AA804 (or AL804) 2GB KIT (1GB x 2) MATCH PAIR PC26400 800MHZ
Video: XFX PVT84GUDF3 Geforce 8600 GTS 256MB
HDD: WD Caviar SE 160 GB 1600AAJS
Optical: Samsung 20X DVD+-R SH-S203B
OS: Windows Vista 32bit Home Premium

Those are the components I have chosen but I would like to hear from anyone who has thoughts about improvements and/or better components and/or compatibility issues.

Also, I was considering adding an after market CPU cooler such as:

Zerotherm BTF90 92mm silent or Zalman CNPS 9500 AM2

and a second HDD to setup a RAID 1 configuration.

A few extra notes concerning the build:

1. Silence is a plus! The quieter the components and fans the better. I would also like to add a couple of extra case fans so quiet fan recommendations are greatly appreciated.

2. The ability to upgrade the processor (and components in general) in the future is a plus. I have read about AMDs Phenom X4 and would like to be able to upgrade to this processor in the future. However, I noticed there are power requirements the MB must meet to allow the installation of this processor (I do not know if the selected board meets those) or should I go with a MB that has the AM2+ socket?

3. I would like to keep efficiency in mind as I rarely turn off my computer. So more than likely it will be running, say 95% of its life. This also brings up reliability issues too, the components should be reliable!

4. I would also like the ability to overclock to some extent. This is not a major concern but if there are slight modifications to components that would increase the ability to overclock I am not opposed, provided the cost is right.

5. Last but not least, the cost of the system above is around $900, about $800 after rebates. I would like to keep the cost about the same but again am not opposed to spending a little more if it means a big gain.

I am not a huge gamer, but I do play some. So, the build is not geared toward gaming specifically. This will be an all-a-around computer doing pretty much everything.

That is all I can think of at the moment. I appreciate any and all comments. Thank you in advance to all who read and respond.
