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 Acer Veriton X2670g as it is running a newer generation CPU. This is not to say that Acer Veriton M4660g is bad - it can still run some powerful CPUs, albeit being an older generation.
Memory
The Acer Veriton M4660g has 4 RAM slots while the Acer Veriton X2670g 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 Acer Veriton X2670g is using the faster 2933 MT/s RAM. The Acer Veriton M4660g 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 Acer Veriton M4660g as it has the ability to run 124 GB of RAM. The Acer Veriton X2670g can do a bit less at max 32 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the Acer Veriton M4660g has 8 USB ports. The Acer Veriton X2670g 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. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
Unfortunately, only the Acer Veriton X2670g has a DisplayPort. The Acer Veriton M4660g does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.
In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.
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 Acer Veriton M4660g is better equipped as it comes with 5 SATA slot(s), while the Acer Veriton X2670g has 3 slot(s).
If you want the fastest transfer speeds for your SSD, an M.2 interface is crucial. Thus, if the M.2 SSD slot is a mandatory requirement for you, go with the Acer Veriton X2670g. Sadly, the Acer Veriton M4660g has no such slot, and you will be forced to use the SATA interface instead.
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
Looking at the Power Supply Unit (PSU) of the two models we don't see any differences. For either of them you get a maximum power of 300 Watts. However be careful, many models have more than one power supply option. When buying your computer, it is a good idea to get a version with the most powerful PSU. This will potentially allow you to upgrade to a more powerful GPU for example.
