are you sure you can still mine 10 block every week? pools are building, and this coin came out only 5 days , it surely easy to mine, but next week and later? pools are building, and lots of miner will coming, 1tb is noting at all, every one can get one, i have purchased 2TB yesterday for next mining, you have only 1.2TB,,loot at the post pages, so many people have TB+ hdd, and one i remember, he has 30TB hdd, of course, he can't creating all plots now,, when every one finished plots creating and innumerable new miners coming, can you make sure that you can still get 10 block a week?
I'm quite sure if you invest 0.8 BTC and get 6 of those servers for one month, let them fill their 6TB each in 10 days, 36TB in total, and mine for another 20 days - you will end up with a lot more than 10 Blocks.
