Question 1

Does this system come with the CPU or must CPU be purchased separately?

Accepted Answer

The BRIX comes with the i7-6500 installed.  You do not need to purchase it separately.

Question 2

Does this have the same problem with fatal WHEA errors that the 6th generation Intel NUC is having?

Accepted Answer

I don't know if it is the same problem as on the NUC but that's what happened so far.
I am on Brix's (i7H) #3.  First one had FanFailure (i7, not i7H). second one (i7H) died after 12 days 24/7 use for no reason. Now this one (i7H) is #3 since 3/29 in use 24/7. 
I like the extra space for the additional SSD inside the box. (Sandisk Extreme 1TB).
Don't know yet what I will do if this one dies too. I know I want to stick with i7 chip-set and I like this small boxes.
Newegg is excellent with refund/replacement.
