Yes, agree with you. Just after analysing all the information before - it became clear for me that mining via GPU or CPU - and cooling systems as well will not guarantee that everything will work perfectly, and that it will give you a great profit. But buying some special equipment - it is also not so cheap, and first you have to offset the cost of all the the equipment and after that only some profit will be yours. And taking into account the fact that you will get 30$ the max per day.... Wow... This is somehow quite sad....
