build a small farm?

... a good cooling system that pays off (in terms of eating less through your wallet)
Not sure if I'll build a farm or not of those but thats always an option. Anyway, I haven't researched the topic of cooling methods other that liquid and air cooling, but getting a number of those 256 mining sets at a bargain price and doing something new, not unique maybe, but that'd be more efficient in overalll, that sounds as a sweet idea to me
