I forget to say i have budget only about 300 +- USD, less is better. As mentioned before i want only cheap toy for mining.
BTW: I have complete free electricity, and becouse of this fact i care only about price per hash with maximal investment about 300 usd, so i found old two mentioned workstations from my neighborhood:
Complete spec is:
Xeon W3565/8GB/250GB for 225 USD 24 month guarancy
or
i5 4570/4GB/500GB for 314 USD 12 month guarancy
I will turn on mining and put it to corridor with ubuntu 24/7.
If you don't care about electricity and you want to mine only YTN, then Xeon W3565 should give you similar results like mine one (500 h/s or more).
Search (or ask somewhere) how many hashes you'll get on Core i5 4570 (IMO something about 450 - 500 h/s, but that's only my estimations, I didn't check it by myself).
