Probably not.
Have you checked the size of the GPU in relation to the SFF case? Alongside that, did you check the slot spacing between the PCI-e slot and the (presumably) power supply lying below it?
An SSD will possibly go if there is a 2.5" slot and/or M.2 connector on that one. I am not quite as familar with the later models of these.
The memory might work. SFF might even be "laptop" memory, so double check what it has and what you are getting.
You would have to order a specific power supply for this unit and it may need proprietary connectors.
What is the reason you are considering updating this machine that way? Are you thinking this will be for gaming, or more power to do office style work?
