Power edge T410 compatibility with Windows Server 2016 and should i buy it ??

I am planning to install a server-client system in my office. Just 5 users. I basically do Engineering design and drafting work (both 2d and 3-d modelling in autocad and solidworks). The following are my priorities: - 1. Prevention of Data loss (No data leakage through USB or any other means). 2. All The data should remain in server before and after working. 3. Seperate working spaces for each person ( receptionist cannot see the files of draftsman and vice-versa). I am getting a secondhand Dell PowerEdge T410 almost unused (4gb ram, 1tb x 6 no hard disk) for $615.

1- I want to know will it be suitable for me.

2. Is it compatible with windows server 2016 essential

3. Any doubt you have about compatibility. Because i have no clue about server-client system. It was suggested by my friend.
