I own a Lenovo M57 which I could use as a dedicated mining rig.

Could I just replace the 280W PSU with a Corsair Builder Series CMPSU-600CXV2 600W ATX PSU, and add an XFX Radeon HD 6970 2GB GDDR5 PCI-E video card?

Or are there problems with these components and my machine, compatibility-wise?

Thank you for your help.  Smiley

I would also go for a 5870, you can pick them up cheap sometimes and they are very good for mining.

Here's a "Mining hardware comparison" chart:

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

Does the case have a standard ATX power supply? And is there an extra case fan (or at least place for it)?

Yes, but you'd be wasting money with a 6970.  You're better off just getting a reference 6950 and flashing/unlocking it to a 6970.

Are you sure this is still the case? The 6950 is only 800MhZ while the 6970 is 880MhZ. Overclocking both, I assume the 6970 will go farther. Right?

In Canada they seem to cost more than a 6970.

There is an extra fan already. I'm not 100% sure that the existing PSU is ATX. I would buy a new PSU though, assuming it fits in the mid-tower of the Lenovo M57.

Based on amazon.ca prices, it looks like my best bet is 2 HD 5830. Thoughts on this?

From what I've seen the 5830 looks good and is one of the highest mhash per dollar

have a look at this

Although the 5870 can generate more and has a higher mhash per watt
