I have purchased one of their most expensive servers but still server is not good , crashed up very frequently , I have done similar setups before , I never faced any problem. In addition to that the worse thing is their support , they have people who dont know how to answer their clients , if your server is down , they will work on same flow as they do .. which really affects your customer. Never go for datasoft , go for OVH (its the best in the world) spend once but you will have peace of mind instead of your server is going down again and again.
