Rule of thumb is a minimum of 1 server with 2 cpu's and 4 gig memory.
Storage on the appserver should be about 20 gig free space.
Such a server can do 8 concurrent report requests by default.

Any additional dispatchers can be calculated by consuming 2 gig mem per cpu.
Every additional cpu can do 4 report requests by default.

A more in depth sizing is usually a payed excersize by consulting companies, so you will probably not get these spreadsheets, as that would give away business.
