Absolutely!
I wanted something to host my private and experimental stuff. A friend of mine who tracks used server auctions pointed me at some servers that were Dell systems clearly custom built for one of the large SV companies. I paid $450 for a box with 72GB of RAM and 16 cores. At that price, I just bought a second one for spares. Which I haven't needed to use in the 4 or 5 years I've been using it.
It has been great.
