Hi Joel Hall,
Concerning the HP ProDesk 600 G3 + vPro depends on the CPU that is build-in.
The i5 and i7 options (listed here: http://www8.hp.com/us/en/products/desktops/product-detail.html?oid=15292277#!tab=specs ) all support vPro.
All other CPU options in that list do not support vPro.
As example, the link you provided also states that the Compute Stick has vPro, but as far as I know this only refers to the Core m5 model. All others do not have vPro.
for the question about all the ATM features, I can not answer. I do not use it.
Regards,
Leon Merts
