For you folks insisting on building your own. A thread for you! I'm looking for a killer Opteron Linux box. Ideas?

I am still considering an Apple Mac, just upgrading my PC.  I wish I could move all those PC upgrade posts over here. Oh well, I'll post followups here - the stuff's on the way.
Opteron Linux? Is that like Red Hat with slinky spring eyeballs?  Sorry, must be late.
Only Poo Bahs and Carpals can create new forums, right?
Thanks Ron!

Ron,
Most of the wintel boxes will run Linux just fine - the configuration depends on what you want to do with it...drivers are less of an issue now that Linux has entered the mainstream...
Alex, Opteron is one of the names AMD has given to its 64-bit processors - which can also run 32-bit code natively...the only reservation I have is that AMD has 2 or three socket forms for the 64-bit processers in the works.
IMHO, the mobos aren't quite ready for Prime Time, but in a couple of months I may be ready to build some PCs with that line of CPUs.

Rusty found this place right away! Overclocking: naw, I tried that with my Soyo and it freaked out. I know it sounds cool to say "I beat AMD out of $129 by overclocking from 300+ to 3200+" -- but who wants to live on the razor's edge of random crashes and runaway heat buildup?
And look at me. The other object of this rebuilding exercise was to lower noise. So I'm going to crank the old variable speed fan up to 6000 rpm and a Canaveral-like 90 dbA for an 8% speed increase ... I still think the MCX462 is loud at 48.5 dB(A) and 4900 rpm. I tuned it down to about half speed.

Tom's Hardware reviewed a handful of AMD64 motherboards. I dropped the ball on the Opteron moniker for the XP64. Asus K8V got a good rating. It is probably too new; Fry's is taking pre-orders. And I didn't even want to know what the chips are going for. Am I correct we gain nothing until the OS and some core apps are retooled for 64 bits? Isn't this like the 32 bit conversion in the nineties?

Alex;
Go to the bottom of the window and check out Extra Information in the Permissions pane. "You can start new topics" should be there.
The Opteron will run 32bit and 64bit code. It ran neck and neck with the G5 so Linux users can rejoice. I believe SuSE has a 64bit Linux out now, but it's always nice to have your apps compiled and optimized for 64bit.
My experience with Wintel hardware (maybe just Intel hardware??) and Linux; as long as you are not bleeding edge you are usually OK. Even then, for sound cards and video cards there are third party commercial folks willing to help out - for a fee. I've found that route to be quite useful at times. Some folks simply refuse to pay for software that runs under Linux but I think a little grease along the way encourages developement and adaption.

Alex, the Opteron will run 32 bit apps just fine. If an app is written to take advantage of the wider path, then the better.
Don't forget that all server manufacturers (IBM, DELL, HP, etc), design specifically for MS Server AND Linux. IBM is on a Linux kick right now so the make sure that all the drivers function correctly and (hopefully) fully optimized.
And they use the Opteron CPU. Go to there eServers site and look around. It will atleast educate you.
Good luck, Tom

Thanks for making this clearer guys - I knew we could run 32bit on Opteron XP64. I was under the impression you wouldn't see the real processing power gains until the 64 bit apps hit the market -- compared to a 32 bit chip at the same clock speed. I saw somewhere the XP64 clock speed is 2GB, which is not faster than the 3000+ model, which would translate to the neighborhood of 2.5GB actual clock speed.
The Athlon 3000+ that should arrive tomorrow is not quite bleeding edge. I'm quite sure my next chip will be 64 bit, though. When the apps and OS are available to take advantage of it, that is.
Ron, Permissions has always said I can start new topics, but it is not hyperlinked and I don't see anything else to click on the pages that would allow me to start a new topic. So maybe I am missing something more elementary -- I am just not seeing a way.

Alex,
Recent Soyo boards aren't known for overclocking potential, but they're generally loaded with features. The DFI mobo probably can handle modest O/Cing. I O/C only to wring the most "bang for the buck".
The MCX 462 is a brute of an HSF, but IMHO, is yesterday's news, as there are lot of more efficient units out there. I'm finding even rabid gamers are tiring of the howl from a Delta fan that creates the sound of a 747 departure.
Now that I've installed the Zalman, I think it's going to be a prime recommendation - the only disadvantage is that the fan is not replaceable. The new MCX462V - with the bent fins - has some promise as it will accomodate a 92mm fan. Still, for the guys that just HAVE to have max cooling, the Thermalright SP-94 with a 119 cfm Tornado (aptly named) should make 'em happy....if they're that obsessed with O/Cing, water cooling is a better bet

Amen Rusty! The rheostat tones down the Swiftech some, but why do I want neighbors in the next town to hear I'm running one of these coolers?

Why? Panache, of course - it's vital in Geekdom that you not only have a Hot Rig, but more importantly, that your neighbors know it...

Alex;
In the main thread topic area, at the top where the title of the forum is at (in this case Computers & Astronomy) you will see a Post lable. That is your baby. Don't make me regret showing you this!

Ron, thanks for your patience with me. On this page for example, where it says "Speciality Forums >> Computers & Astronomy", I do not see a Post label. Never have seen one. Some BB's do not dole this out til you've been around a while. I don't even have a hundred posts yet. You had a hundred posts before you were old enough to kick the slats out of your crib.
Rusty, the DFI Lanparty NFII Ultra and the Zalman CNP57000A-AICu arrived today. Problems. I will PM you but it looks like a drive down to Fry's Saturday! Oh Well ...

Alex, we gonna make a Geek of you yet (I hope you have a case with UV lights and a window, so's the colors of that mobo can be SEEN! [Very important in Geekdom]). 
So what are the problems? The DFI mobos come with just about everything.
Anyway, you're going to like the Zalman - and it's very easy to install - but check the instructions BEFORE you mount the mobo to the case...
If Fry's has Arctic Silver, try to get AS 5; if not, the thermal paste supplied is OK, but Arctic Silver 5 will run the CPU about 5-7 deg C cooler than the stock.

Dang, don't you Florida guys ever sleep? The DFI mobo does come with about everything except four mounting holes. The Zalman website doesn't even list a DFI model number beginning with the letter "N" as in NFII Ultra.
Unless I'm missing something (it's happened before) I may have to swallow my pride and drive into Fry's with a convincing "Oooh I'm so sorry" Customer Service supplicant expression.
I've made a note to get Arctic Silver. I thought it was just an image thing!

Alex; what if you back up one level to where the listing for computers&astronomy are. Post should be there. If not, I'm sure it's because of your draft status, unauthorized tatoo or meade ownership.

Users.... 
If Meade and Celestron are the Apple and Microsoft of the telescope world, is the dob our version of Linux?
