No argue about worth it or not for buying mining rigs nowadays.
To be honest, with all of that spec, $3000 is a reasonable price (if it right), you've reduced rig building time that will take a long enough time if you were do it yourself. On this bundled, each GPU cost you under $300 (not bad), but we don't know are those cards brand new or used card.
Let's see what they are gonna tell me.
I am gonna ask them for further details through E-mail conversation
Waiting for the result!
I am not saying that they are right or Wrong but as you stated about specs, for $3000 and 6-7 months ROI that is way better than homemade or another custom mining rig
after 3-4 days of enquiry
and they told me that these cards are new and custom made for mining
I ordered Two G12
