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 Acer Veriton M6690g as it is running a newer generation CPU. This is not to say that Acer Veriton M6660g is bad - it can still run some powerful CPUs, albeit being an older generation.
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 Acer Veriton M6690g is using the faster 3200 MT/s RAM. The Acer Veriton M6660g 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 M6690g as it has the ability to run 128 GB of RAM. The Acer Veriton M6660g 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 Acer Veriton M6660g has 10 USB ports. The Acer Veriton M6690g 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. 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 Acer Veriton M6690g as it has 2 USB3.1 ports (the Acer Veriton M6660g has 1).
The DisplayPort is usually the more popular video port used with desktops and laptops, while the HDMI is used predominantly in consumer electronics. That's why, it is good to see that both of the models come with a DisplayPort.
In case your monitor supports HDMI only, you will be happy to hear that both models come with an HDMI port.
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 5 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 Acer Veriton M6690g has 1 M.2 slots while the Acer Veriton M6660g 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
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 500 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.
