ssd upgrade for hp compaq pro 6300 sff

[extreme_noob]

I am thinking of getting a samsung 860 evo 250 gb ssd for my hp compaq pro 6300 sff. I plan on keeping the hard drive in for files that i don't need to load quickly. the 6300 sff has 1 sata 3.0 port, 2 sata 2.0 ports, and 1 esata port. It comes with a sata III hdd and an optical drive. First of all, I was wondering whether the 860 evo is even compatible with my pc, and second I was wondering where to plug everything.
