No, no it is not.
I am not sure why
@semidetached said that it has an Intel board, because it most certainly is not. The board inside is made by Gigabyte, and is similar to the QBiP-1115G4EB motherboard or the board used inside of the GB-BSi3-1115G4 that

Point on this doll where the mPCIe slot hurt you. Seriously, it is a weird thing to be so upset about. I am honestly happy that it has a variety of slots to use. I personally will use that slot for an mSATA SSD, freeing up the M.2 M-key slot for a larger drive.
Seneca had a whole bunch of products, some were more full-fat PCs like this one, and some were tiny thin client devices. They whitelabeled a good amount of gear, as I have seen Seneca branded Lenovo 1L PCs, Seneca branded Intel NUCs, more industrial stuff like these boards based on Gigabyte stuff, and very small Apollo Lake based Celeron thin clients.(Search for Seneca N3350D)
