For start up VPS hosts, I will always recommend something along the lines of the following:
(optional) 1x128GB SSD for Flashcache
Something along the lines of that will serve well, and also be future proof.
Another option could also be a Dual E5-2620 with 64GB RAM if you really want to go up, and have the budget.
I maybe would increase the RAM to 64-128GB. Processor is good and storage looks acceptable depending on configuration. if using raid i dont think 1tb would be sufficient for the amount of customers you will need to make the server viable. Then we are in the realms of overselling
