it is so nice to have your feedback. That is a very impressive points count.
I am glad it works out for you. I would say the SSD definitely helped a lot as well.
The spec of your server is not too hard to obtain anyway which is good.
Did you use the Windows Service (auto startup) component mentioned in Mango's help instructions?
I am curious how you tested it with a second PC before you upgraded the system.
I am guessing that you ran both PCs at the same time since all your DSs are IP based.
You should write a user-case for the forum 'Stories' section as well. that will be nice.
