A:AnswerThank you for reaching out. You will want to specifically pull up the service and maintenance guide for this PC on support.hp.com and inside that manual will list the part number for the SATA to M.2 adapter.
A:AnswerYes unfortunately all the USB ports are on the back but it's really not a problem. I use the usb's also for my work. This computer is really a good buy and I am glad I got it.
A:AnswerThank you for your question. This model does not have the ability to have a GPU added for you. You would have to get the model preconfigured that way for you.
A:AnswerDid you finish setting it up?? Did you go through all the steps? Did you register it, sync it to your phone? Ask Cortana to “finish setting up”!!
