I want to create a NAS by myself, for about 4-12 TB of space, depending on what it will cost. I see that I can buy hdds for 3TB now, but how can I know if the motherboard will work with it, and how many of them it will be able to work with.

This question came from our site for system and network administrators.
You can usually lookup the board on the manufacturers website and it will specify the maximum size. Generally, if it doesn't specifically say it's compatible with drives larger than 2.2TB then it isn't.
Other than that, the only motherboard limit would be the number of drives you can connect to it.
There may be logical limits imposed as well (depending on your OS, file system, etc).
