can't look at book am offsite. first use 2 ports you have to start. buy a pcie SATA controller for the other 2. that gives signals. use internal Dvd power plug and get a Y or other cable. if that not possible, buy cheapest enclosure you can find to supply power and house ssds & just get 4 long SATA cables and route them any way you can. this may be easiest for you.
it is not rocket science. relax, all you need to do is power and signal them in any enclosure. no need to worry about temperature and EMI
