Both models have the same form factor, meaning reoughtly they have the same phiysical size and form.
Processor
Usually the newer the generation of the CPU, the better the performance and efficiency is. If your budget allows it, you should go with the Dell Vostro 3881 as it is running a newer generation CPU. This is not to say that HP EliteDesk 800 G5 Tower is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The HP EliteDesk 800 G5 Tower has 4 RAM slots while the Dell Vostro 3881 has only 2 slot(s). This is not something to worry about. Just make sure you take it into consideration when planning how much RAM you are going to use.
The Dell Vostro 3881 is using the faster 2933 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 Dell Vostro 3881 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 HP EliteDesk 800 G5 Tower has 11 USB ports. The Dell Vostro 3881 is inferior in this regard and packs 8 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the HP EliteDesk 800 G5 Tower, is that it has 5 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the Dell Vostro 3881 has no such port, thus restricting your transfer speeds significantly. For people who want to use external drives on regular basis, this might be an issue.
Unfortunately, only the HP EliteDesk 800 G5 Tower has a DisplayPort. The Dell Vostro 3881 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
The Dell Vostro 3881 comes with an HDMI port, while the HP EliteDesk 800 G5 Tower does not support the interface. Of course missing HDMI port is something that can be easily fixed with a good adapter (e.g. DisplayPort to HDMI).
SATA ports are placed on the system board and it is where you connect your HDD, SSD and Optical Disk Drives. More SATA slots will allow you to have more drives running at the same time. In this regard the HP EliteDesk 800 G5 Tower is better equipped as it comes with 4 SATA slot(s), while the Dell Vostro 3881 has 2 slot(s).
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 Dell Vostro 3881 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 Dell Vostro 3881 comes with a decent 260 Watt PSU, but the HP EliteDesk 800 G5 Tower has a more powerful one rated at 500 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.
