Hey Gang,

I've been looking things over and I am aiming to build a light mining rig with hopes for future expansion. I am a self-professed newb and so I am hoping to get a little help from the community with my choices of hardware. As far as I know, the hardware I have chosen should work together, but if anything sticks out, constructive criticism would be greatly appreciated.

What I have here is a combination of what I found on these two well-known pages:
https://en.bitcoin.it/wiki/Mining_rig and:
https://en.bitcoin.it/wiki/Mining_hardware_comparison#See_Also

Also, I am in Europe and some of the hardware is either unavailable to me or prohibitively expensive. Links provided go to a Czech website, but I think the specs should still be intelligible even without translation. Here is the list:

-Mobo: ASUS M4A87TD

I know the HDD is quite an overkill on space, but it was one of the cheapest they had that appeared worth anything. My goal is to firstly have a machine that has high Mhash/J, which is more important to me in the long run considering the costs of electricity, and then secondly, to have an initial investment that gives me a high Mhash/$ invested. I figure with the HDD, I can simply remote access it and use the extra space as storage.

Also, as I am just getting my feet wet, I do not want to immediately invest too much until I get a feel for the practical side of this operation. To that end, I have been planning on building my own PC anyway and so if I decide to bow out of mining, most of the components I plan to buy can be used for my home office/gaming rig. I calculate my bitcoin mining investment portion of this machine to be only about USD 200.

Based on the motherboard I have chosen, would it be possible to add another 1 or 2 of the same GPU if I decide to take this further? I would like to get close to the ~420Mhash/GPU that I have been reading in this thread and so I plan to have the appropriate software and configuration there.

Thanks for any pointers!
