'Best' Mining Rig?

[dollartrader]

I'm currently in a situation where I have 'free to me' power. Probably for the next 6-8 months. If I could tuck a rig away in the corner solely for mining 24/7, what should I get?

Would be nice if once the 'free power' goes away, it'll just be a desktop suitable for gaming.

edit to say: I am looking to buy a new desktop, occasionally will be used for gaming although I'm not a huge gamer. So, thought I'd get one now, use it for mining and later would become my primary desktop.

Current exchange rates are garbage. If you already have the hardware though, then at current exchange rates and difficulty, you get about $0.25 per 100 mhash per day.

If you don't have the hardware, then, say, a 1 ghash rig will probably set you back I'm guessing $500? At the above rates, it'll take 200 days to make your money back and break even.

Thanks for the quick reply, I edited my original post to say that I am looking at buying a desktop so monies will not be spent solely for mining.

Hadn't planned on getting one yet but if I can snag one now that is going to pay for itself then I may as well do it, just looking for the most bang for the buck.
