Well, maybe ill go microATX then. Bigger case, potential for another card, better airflow, stronger miner!

thanks guys. Yeah a 5870 would be great if I came across one. I have limited knowledge of mini-itx, are there mini itx boards that support crossfire?

Um, yes, I know that everything that is not a video card in this computer is not making me money. However, in order to use a video card I need a system to run it in do I not  Not sure if I understand what that comment is supposed to mean. But this is about as cheap as one can get given the circumstances

I'm not gonna blow $4000 on a dual 6990 system with mining difficulty growing at such a horrific rate.

An extremely small, sub $400 system that can mine at at least 200+ m/hs 24/7 pooled sounds pretty effective to me.

And 5000 series video cards are still plentiful enough, maybe not new of course, but there are several websites that would allow me to acquire a used one.

5830s are better m/hs are they not?

hmmmm. Thanks that is something i didn't consider. I was also thinking about just using windows 32 bit

Hi everyone. Just registered as I get more and more serious about mining.

Check out my post of mini itx mining rig I have ready to purchase, I need some tips and recommendations. Thanks!

Hi, review this list

https://en.bitcoin.it/wiki/Mining_hardware_comparison

Its contains all graphics cards and specifications in terms of mining.

I have a similar post to yours, you may be surprised to see that some lower end cards can perform almost as well as higher end ones.

Hi all, I just registered today as I get more and more serious with bitcoin mining. Lucky for me, in my current location I already have access to a system with one watercooled 5970 ( ) thats been running for about 36 hours now.

Each core of the 5970 has almost 8000 shares from slush's pool. They're mining away at avg 500+ m/hs.

Anyways, fortunate for me my other home has solar panels which lower the electric bill to a fraction of what it once was. This allows consideration of electrical cost of mining rig to be almost nonexistent.

I was hoping to see what everyone else on here thinks of this current 24/7 Mini ITX mining rig I've put together on newegg. (assuming almost everyone on here has an exceptional knowledge of computer hardware + bitcoin mining)

As the video card is the most essential unit in a mining rig, I have yet to decide on what that will be. I am considering a 5770, 5830, 5850, or 5870. However I have yet to find that irresistible deal on one that will make this all become a reality. I'd like to get at least 200+ mega hashes out of the card. The rest of you scoundrels have swept up all the remaining 5970s and 6990s from the market  

So let me know what you guys think about my current setup/situation/goals. Thanks!
