I saw the same thing and pulled the trigger on it (mine) so I should be receiving my server at end of next week and can potentially give you some feedback after I get mine going.
here is what I already know: in order to use more than 2 cpu cores - you will need to use winserver (such as win server 2012 standard) and not win10/7/8. You -can- probably install your software on winserver but you should at least test in a virtual machine first since your software is probably only for win7/10.
It will be loud and probably also output a nice amount of heat. I'll be putting mine in a back room where I can have a window open during winter.
Also, some programs may have problems running more than 64 simultaneous threads as this is a windows logical processing "group" so if code isn't set to handle this then you strange things may happen like only half the threads get activated. if I have this problem then I may default to turning off 1 core in the bios which would put me down to 30cores/60threads as opposed to 40/80.
