Just about any Windows 10 PC can be used for viewing cameras only.
I do not trust ads that do not provide all the information. What Processor , there are a number of 4th gen I5 processors.
I would recommend that the PC have an HDMI output, for this computer you will need to an a display port to HDMI converter.
What type of software are you going to use to view the cameras ?
How far are the cameras from the computer ?
Are the cameras WIFI or hardwired ?
