I purchased this HP ultra small desktop PC so that I could use the MXM PCIe slot for mobile GPUs.  The system runs with an Intel i7-4770 with 16GB (2x8GB) of DDR3 SODIMM RAM. The GPU used is an AMD Radeon Pro WX 4150 4GB GDDR5 mobile graphics card.  These seem to work easier with these HP's more so than the Nvidia mobile cards.  This is older hardware, but it is loaded with the most up to date Windows 11 Home and is activated.  The operating system is loaded on a 512GB mSATA SSD, so it is snappy.  There's also an included 1 TB HDD, for extra storage.  Overall, this is a great desktop PC that can be used for light gaming and workstation applications.
