Will this fit my needs.

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 ?
 
that system only has room for a single 2.5 inch drive. A poor choice for blue iris. Furthermore, 145 for a 6 year old pc is a ripoff.
make a best offer on this one. Says no os, but its licensed for w10. Simply use the MS media creation tool.
