I must admit you are working with a failry bare system (as in not a big video card sucking power) But I hate to say it. I just wouldnt go with anything less then a 500. Your system should use about 300watts (most OC's will take some voltage tweaking, and yess 300 watts is a bit high, but I would rather guess high then to low) so at 80% efficency thats 320 watts... you are right on the edge, so your PSU will be working at its 100% load (almost). I know most will do that just fine, and Enermax is a good enough PSU brand. I would guess my figures are worst case and that PSU would probebly last forever, but a few more watts would really give you a much more overhead.  I work and build systems (how I make my money) and PSU are one of the worst headaches to find, fix on unstable systems. Again, it looks like a nice build to me, looks like you are going rebate crazy (so price will be even better then your list when you get um all back). I have a E7500 but have yet to play with it, I do know the 8400 are wonderfull to OC and mine have been rocks. I build more "gameing" systems with 8400's then anything else and almost always get an OC of 4Ghz out of them with close to stock voltage (personal machine for gaming is runing 4.2 at stock (but its the excpetion, not the rule)).

Again, I think you are fine, but I would bump the PSU for peace of mind (but you may just be fine).  Really looks like you ahve done your research to me. Great Bang for Buck!!!!

Excellent. Thanks for the response and advice. What would be the difference in a $32 RAM and the $50 RAM I listed above, in terms of overclocking? Like:
OCZ System Elite 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2SE8002GK - Retail $32

Oh, and I seldom account for the rebates when I am pricing anything. They are such a pain to get and take so long that I usually don't even consider the rebated price when making my budget. Then when/if the rebate does come it's like free cash to me.
clok:
The cheaper stuff is older OCZ, i notice there is no warrenty info listed, possilby only throuhg OCZ on that stuff? Older OCZ memory is known to be fussy. That memory has older specs (lower voltage) so its possilbe it wont work in your board. It should but.... Its slower all around but for waht you are doping that shouldnt matter. I use gigbyte boards myslef for my peresonal machines(for OC and customer rigs, have had great luck). But I did have some OCZ memory (older stuff actually) that didnt work in one of my boards.  if you are looking to save a buck... great reviews and cheap.

I placed an order with Newegg for my shopping list above. Three longs days later I was like a kid in a candy store with all my new parts. I was hoping that this post would be about my benchmark results, but instead it was mid-assembly when I noticed that the CPU cooler was missing the mounting bracket for the 775 motherboard. And it wasn't until after I liberal applied the thermal paste that I realized this. I would have continued without the cooler for now until I could get a replacement delivered, but then I found a problem with the hard drive (I already had one) that I thought I was going to use.

So I'm stuck with a mostly assembled machine. Once I get the correct mounting bracket I am sure I will need to remove the old thermal paste and apply new again. Argh. The frustration begins.

After I got the hang of getting my BIOS settings correct, I was able to get my above setting to 3.6GHz with the stock cooler and almost NO tweaking even necessary.

I am having a hard time with the Core-Contact Freezer CPU cooler because I received it without the retaining ring. I have left four messages (on four separate days) with Sunbeam Tech at their "customer service" and RMA number so far without a single response. I can return the cooler to NewEgg and have a new one sent, but that is going to cost me another $8 for return shipping, which is an additional 20% of the original price. I just don't feel I should have to pay extra because they screwed up and sent me an incomplete package. So I installed the stock Intel cooler for now.

On OC news, all I did was set the frontside bus to 400MHz, multiplier to 9X, and voltage to 1.3725 I think. The trick I was having was in getting the memory setting correct. Once I got the memory to a 1:1 ratio and set at 400MHz with a multiplier at 2, all was golden. I ran Prime95 at 3.6GHz and hit temperatures in the mid to high 50's at full load. I think this is highly do-able, since in all practical use both cores will not be at 100% load for hours at a time.

Once I get the new cooler situated I will bump the multiplier to 10X and see if I can get 4GHz stable. That is my goal.
