I know nothing specific about this computer but I notice a few things to pay attention to:

There isn't a very extensive description of exactly what is included in this machine.

You will need a monitor, Starting at $169.00 from the same source.

You will need to buy Microsoft windows and Office in order to have the ability to do a "powerpoint" presentation, at $189.00 from this site.

Now we're pretty close to $600.00 total. Not a bad price but comparable to what you might be able to find at your local Best Buy for a similar quality of product and the local store might be easier to get questions answered at for a computer purchasing newbee.

I might give the school a call and see if they have a way for him to put this together without you having to buy a home computer unless you already want one, or it will be very necessary in the future.
