If you are looking for the smaller form factor the Alienware Aurora R8 is the right one for you. It is smaller than the HP EliteDesk 800 G5 Tower and will fit more easily under your desk.
Processor
The two models have the same generation of Intel processors. We think that the 9 generation of Intel Processors have enough power to execute all of the home and office tasks that most people will care to do.
Memory
Both models have have equal amount of ram slots (4 RAM). Usually two RAM slots are more than enough for most cases. However, the count should be taken into account when planning how much and what combination of RAM you are going to need for your system.
The Alienware Aurora R8 is using the faster 3000 MT/s RAM. The HP EliteDesk 800 G5 Tower is slower by supporting RAM speeds of up to 2666 MT/s. Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G5 Tower as it has the ability to run 128 GB of RAM. The Alienware Aurora R8 can do a bit less at max 64 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Alienware Aurora R8 has 12 USB ports. The HP EliteDesk 800 G5 Tower is inferior in this regard and packs 11 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. It's great that both of the models have USB 3.1 ports which will allow you to exchange data with your peripherals at up to 10Gb/s. But if you need maximum connectivity, go with the HP EliteDesk 800 G5 Tower as it has 5 USB3.1 ports (the Alienware Aurora R8 has 2).
Unfortunately, only the HP EliteDesk 800 G5 Tower has a DisplayPort. The Alienware Aurora R8 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
None of the models has an HDMI port. If your monitor supports only the HDMI interface, you will need to buy an adapter. Such adapters are cheap so nothing to worry about.
SATA slots are located on the motherboard and it is where SSD, HDD and Optical Disk Drives are connected. Each of the two models being compared have 4 SATA slot(s). Keep in mind that having too few SATA slots might limit your options for connecting additional memory drives.
An M.2 SSD can be several times faster than a SATA one. Thus, we are happy to see that both models support the M.2 interface. However, the HP EliteDesk 800 G5 Tower has 1 M.2 slots while the Alienware Aurora R8 comes with just 1.
Make sure that the available M.2 slot supports the PCIe (also called NVMe) interface. This is important as there are M.2 slots which support only the inferior SATA III interface. For comparison, the SATA III interface has max speeds of 6Gb/s, while the PCIe 3.0 x4 will support speeds up to 32Gb/s!
Power Supply
Having a Power Supply Unit with high power rating is important, if you are going to use components which require extra power. The HP EliteDesk 800 G5 Tower comes with a decent 500 Watt PSU, but the Alienware Aurora R8 has a more powerful one rated at 850 Watts. Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
