First time builder looking for advice and

Well I can't see your items in your link. It's on a secure site and not on the public one. What is your budget and what is your purpose of this PC? Can you list each individual part and links?

You need to make your list public and check the share option.

Here is the wishlist as-is (the WishlistID doesn't change when you make it public, so I went to another public list and changed the ID).

Case: APEVIA MX-Pider MX-PIDER-BK/500 with 500W PSU - $110
PSU: Included with case
Motherboard: ABIT AB9 Pro - $90 - $30MIR
Video Card: HIS Radeon HD 2600PRO 512MB - $70 - $20MIR
CPU: E6550 Retail - $170
RAM: Patriot 1GB DDR2 800 - $28
Patriot 2GB DDR2 800 - $44
HDD: Seagate 7200.10 500GB - $100
Optical: ASUS DVD/RW - $27
Network: Encore WiFi adapter - $40
TIM: Arctic Silver 5 - $6
HSF: Scythe SCINF-1000 120mm CPU Cooler - $40
Total: $725 - $50MIR

Keep in mind, I like the fact that it looks like you've done some reading on this, and that you're asking for more input.

Le sigh....I'm glad you asked advice. There are many places for improvement in your build. It looks like you've done some reading, and possibly taken away some wrong conclusions. Also, it looks like you've chosen mostly the cheapest component. Less expensive isn't best, or even a good idea many times.

First off case/power supply. The case seems fine, but the power supply is an unknown quantity. A reliable PSU is one of the most important pieces of a new computer. So my recommendation is to get a different case, and a solid PSU. For example:
Original choice: APEVIA MX-Pider MX-PIDER-BK/500 with 500W PSU - $110
My suggestion: NZXT Apollo Black - $70 - $20MIR and Corsair 550VX - $85 - $15MIR
Price difference: +$45 (+$10 after MIR)
Alternately, if the look isn't important, you can get the Antec Sonata III - $130 - $30MIR with the Antec PSU (pretty reliable). In that case you're looking at a price difference of +$20 (-$10 after MIR)

Motherboard: Your choice seems fine, however I would suggest a somewhat more modern chipset. A P35 board will give you more choices for future processors.
Original Choice: ABIT AB9 Pro - $90 - $30MIR
My suggestion: Gigabyte P35-DS3L - $90
Price difference: Even (+$30 after MIR)

Video card: It looks like you went price over performance. A best buy for under $100 would be the Radeon 2600 XT, not the pro. Even if you went with the pro, you should look at the DDR3 card, not the one you had listed.
Original Choice: HIS Radeon HD 2600PRO 512MB - $70 - $20MIR
My suggestion: HIS Radeon 2600XT 512MB DDR3 - $95 - $25MIR
Price Difference: +25 (+$5 after MIR)

CPU: This is a decent choice. However, with a little work on your part you can get a cheaper processor that runs better than an extreme edition. You do have to overclock though. That might be intimidating, but this forum has some excellent guides, and a simple overclock can be done in less than 30min.
Original Choice: E6550 Retail - $170
My Suggestion: E2180 - $78
Price Difference: -$92

RAM: This is where I really think you read some stuff about 32 bit OSes not being able to use more than 3GB of ram. That is true, but not the important part of the idea. You can put more than 3GB in your system, the OS will just not be able to use all of it. However, there are performance benefits to using matching RAM (dual channel and whatnot).
Original Choice: Patriot 1GB DDR2 800 - $28
Patriot 2GB DDR2 800 - $44
My Suggestion: A-DATA 4GB(2 x 2GB) - $70
Price Difference: -$2

HDD: This is also a decent choice, but for the same price you can get a better performing drive. The Seagate 7200.11 is superior.
Original Choice: Seagate 7200.10 500GB - $100
My Suggestion: Seagate 7200.11 500GB - $110
Price Difference: +$10

Optical drive (DVD): This is a perfectly fine choice.

Network card: Again, no comment. I don't know enough about them to suggest one. You might be able to find a USB-wifi adapter for less, but other than that I can't say anything.

TIM: Good choice. There is some discussion about other products being better, but AS5 is solid and proven.

HSF: Not the best choice. There are better and less expensive HSFs out there.
Original Choice:
My Suggestion: Xigmatek HDT-S1283 - $37
Price Difference: -$3

So, to summarize:

If you don't want to overclock, you can drop the HSF, and get a better processor than I've listed. Also, if you're running XP, you can go with 2GB of RAM, leaving room for more later if you want while still saving money.

Non-Overclock idea, with cooler looking case:

Case: NZXT Apollo Black - $70 - $20MIR
PSU: Corsair 550VX - $85 - $15MIR
Motherboard: Gigabyte P35-DS3L - $90
Video Card: HIS Radeon 2600XT 512MB DDR3 - $95 - $25MIR
CPU: E6550 Retail - $170
RAM: G.SKILL 2GB (2 x 1GB) DDR2 800 - $45
HDD: Seagate 7200.11 500GB - $110
Optical: (No change) ASUS DVD/RW - $27
Network: (No change) Encore WiFi adapter - $40
Total: $732- $60MIR
Price Difference: +$7 (-$3 after MIR)

You may be able to find better deals with shopping around. This is intended as a guide for changes, and an idea of the impact you'll see on price. Not all of the items I linked are from Newegg, so there will be changes if you only want to use one vendor.

I think if there isn't any OC'ing than a AMD build might be in order. I'd go with this setup, if you want to consider a AMD build.

Total $760 - $100 MIR's = $660!!! Much better system than getting a 2600xt GPU on the previous 2 builds. For gaming, in general, you'll want the best GPU that you can afford. I believe this build will fit into the mid range gaming rig, especially since I've included the 8800gts (g92) GPU.

If you need to trim the fat from your budget then go with the 9600GT for 179 bucks. It will be plenty of video card for that setup...

What exactly is this rig going to be used for and what is your budget?

If not OCing, I like lunyone's build except I would ditch the Freezer 64 Pro and get the non-black edition 5000+.

If you don't mind OCing, I would prefer litlrabi's E2180 build. You could even stick with the stock cooler and put the money saved from the cooler towards a better GPU if this is meant for gaming.

If your OCing you could go with the E2160 or the BE 5000+. Either will OC very well for a low budget. You will come out cheaper with the E2160 tbh. 59 vs 79.

Hey guys appreciate all the responses. As you already know I am a first timer and all the feedback is much appreciated.

I plan on using the unit for HD video 1080p x264, remuxes of HD Dvd and BluRay.

I would also like to maintain onboard fiberoptic audio. I am curious if their are advantages to getting a seperate audio card.

AMD or Intel works for me as long as it will be effeient for my needs.

As far as GPU's im not sure how extravagent i need to go. I know i will need at least to DVI outputs.

I would like to keep the cost under $800 if possible.

So once again guys thanks for everything, i apologize for my absence, i have been outta town and caught up with other things. Any other insight will be much appreciated!! Thanks!!

Here's a good deal on another 2600XT w/512 mb or ram. Just got mine yesterday, haven't got my board yet though.
