This is not to say that HP ProDesk 400 G5 Microtower is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
Both models have have equal amount of ram slots (2 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.
None of the desktops has an advantage when it comes to the speed of the RAM being used. Both models support RAM speeds of up to 2666. Additionally, if you will be needing a lot of RAM, better go for the HP ProDesk 600 G5 Mini as it has the ability to run 64 GB of RAM. The HP ProDesk 400 G5 Microtower can do a bit less at max 32 GB.

In total the HP ProDesk 400 G5 Microtower has 8 USB ports. The HP ProDesk 600 G5 Mini is inferior in this regard and packs 7 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. What is nice about the HP ProDesk 600 G5 Mini, is that it has 4 USB 3.1 port(s) which allows transfer of up to 10Gb/s. Unfortunately, the HP ProDesk 400 G5 Microtower 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.
DisplayPort is crucial for any desktop machine. It is good to see that both models are featuring DisplayPorts. However, the HP ProDesk 600 G5 Mini comes with 2 ports, while the HP ProDesk 400 G5 Microtower has only 1. If you are planning to use multiple monitors, the HP ProDesk 600 G5 Mini is the better choice.

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 ProDesk 400 G5 Microtower is better equipped as it comes with 3 SATA slot(s), while the HP ProDesk 600 G5 Mini has 1 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 ProDesk 600 G5 Mini has 1 M.2 slots while the HP ProDesk 400 G5 Microtower 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 ProDesk 600 G5 Mini comes with a decent 65 Watt PSU, but the HP ProDesk 400 G5 Microtower has a more powerful one rated at 310 Watts. Choosing either one depends on your specific requirements and use case.
