There are tutorials on youtube for that. I think VMware has an official channel that has a small series on vSphere/ESXi.
I just finished installing Dell's version of ESXi v5.5 on my PowerEdge 860 after my boss recommended I go with that over my beloved virtualbox. Bare-metal VM is FAR better. Definitely a noticeable difference in performance on my VMs. The catch is some limitations that come with the free version, and the fact it's a little harder to use than something like virtualbox if you're not very experienced with this sort of thing.
Installation is pretty straight-forward honestly. You burn the ISO to disc, pop the disc in your server, reboot, run the installation, reboot, and you're done. When you boot up the server it will boot to the ESXi main screen which contains the information needed to connect via web client or vSphere Client. I use the latter on my personal/gaming rig. It gives you complete control over ESXi.
IIRC the free version is limited to 1 cpu. I do not know if this means 1 CPU per VM or ESXi can't be installed to a host with more than 1 cpu, but I am leaning towards the latter which is rather unfortunate. There is also a limitation on RAM and cores allocated to each VM but they're really high, like 256gb/16core or something along those lines.

Check that out and see if your server is in the compatibility list. Mine was not but the dell drivers bundled with that ESXi are widely used across numerous platforms in most cases so my PE 860 ended up being unofficially supported. If you go this route you'll still need to make an account over at VMware's website and check out their vSphere/ESXi 5.5 page so you can fetch your free license key.
