Im not sure what motherboard it uses (although from the size I'm guessing mini-ITX?) but just a word of warning, the free upgrade to windows 10 means that the computer is going to accept very few, if any, hardware changes before it requires you to buy a new copy of win-10 outright.
Twig[/quotemsg Appreciate the response. I believe I'm going to revert back to Win 7 anyway. I found that the MB has a DIG43L designation which would make it a Micro-ATX. But since this is a All-In-One Touchscreen, would I be able to use a Micro-ATX with an 13/15/17 CPU with Integrated Graphics (e.g. GIGABYTE GA-B85M-Gaming 3)
