With the current scale of your company, it is enough to buy an entry-level server (enough to meet the demand and even leave a lot of redundancy), and there is no need to buy a server with higher configuration. Of course, the choice of brand is very important. Server brands recommend IBM (preferred) and HP (alternative). The specific models and approximate prices are as follows for your reference:

Choosing a rack server can save your computer room space. Buying a standard cabinet with a height of 1.2M can put your company's servers and all network equipment in it, which is beneficial to centralized management.
IBM and HP are the best server manufacturers in the market. If you want to further reduce the cost (excluding the possibility of reducing the configuration), you can also choose brands such as Dell, Lenovo and Inspur.
Office computer configuration:
The mainstream commercial desktop brands are mainly HP, Dell and Lenovo, and other brands are not as good as these three brands in terms of shipments and popularity. Moreover, the commercial computers of international manufacturers are good after sale.

External network device (router):
Your company is large enough to use small and medium-sized enterprise routers. H3C is recommended.
H3C ER2 100 enterprise router
Internal network equipment (switch)
The same products are H3C, H3C S 1026T Gigabit uplink switches. Baidu can only post a picture once. I'll give you a link.

The server is set as the server side of the network version of antivirus software and multiple roles such as file server and database server. Because the number of users in your company is limited, there is no problem with this setting.
Software firewall and antivirus software are recommended to install NOD32 security suite online edition. As for the restoration of users, personally, it is unnecessary to make it so complicated. After installing online antivirus software and firewall, install another security assistant software such as 360, then disable USB storage devices in the registry (disabling USB in BIOS will disable USB keyboard and mouse at the same time), and finally make a one-click Ghost backup of the system disk.
The method of disabling USB storage device: enter "regedit" in the running dialog box, open the registry editor after entering, expand the following branches in turn [HKEY _ local _ machine \ system \ current control set \ service \ usbstor], find the DWORD value named "Start" in the right pane, double-click it, and modify its numerical data in the pop-up editing dialog box. Click OK to close the Registry Editor and restart the computer for the settings to take effect. After restarting, when someone connects the USB storage device to the computer, although the indicator light on the USB device flashes normally, the drive letter cannot be found in the resource manager, so the USB device cannot be used.
