HP EliteDesk 800 G4 SFF
Specification and Upgrade Options
The HP EliteDesk 800 G4 SFF is a pre-built business desktop computer first released in 2018. Although more than five years old, it is still a viable solution for home and office. The motherboard is using the Q370 chipset and supports 8th gen Intel Core processor, 64GB of DIMM DDR4-2666 memory, and a low profile GPU. You can even make a gaming PC form this machine with a proper GPU upgrade.
HP EliteDesk 800 G4 SFF is a Small form factor computer. The Small Form Factor (SFF) is an in-between model. It has less space for the larger form factors (Mid tower, Mini tower, and Desktop), but it is still easily upgradable. Usually the SFF come with 2x PCIe slots, so fitting a low profile graphics card is possible.
Can you upgrade HP EliteDesk 800 G4 SFF to play games?
Yes, you can upgrade HP EliteDesk 800 G4 SFF for gaming with better processors, graphics card, memory, and storage devices. However, like many other business pre-built PCs, this model may have proprietary elements like the power supply, the chassis or the power connector, which can make it difficult for users to install aftermarket PSUs to support better GPUs. You can also find that there is space constrains inside the chassis, making it difficult to accommodete larger GPU to boost the gaming performance.

Ports
Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.
USB ports
The HP EliteDesk 800 G4 SFF comes with eleven USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. It is nice to see that the model has a USB 3.1 port. This interface is using 10Gb/s connection and it's very useful when you transfer big files to external drives.
Video ports
The DisplayPort (DP) is the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the HP EliteDesk 800 G4 SFF is featuring a DisplayPort 1.2. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.
The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the HP EliteDesk 800 G4 SFF doesn't have one. This is not a problem if there is on-board DisplayPort.
*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.
SSD storage - M.2 sockets and SATA ports
The SATA port is one of the places where you can connect a stora gedevice. The HP EliteDesk 800 G4 SFF comes with three SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.
HP EliteDesk 800 G4 SFF has also two M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
Best PCIe NVMe drives for HP EliteDesk 800 G4 SFF storage upgrade:
