Looking at how old the system is, the chances of resell are slim. Your ram is the original ddr, where the current standard is ddr4 (several times faster) and the processor is really bad. A smartphone may be able to beat this PC. I personally wouldn't buy it as a server because of the power draw vs performance alone. I could probably buy one of those compact PC's with better power efficiency. However, if someone is in need of a PC for normal use and is cheaping out on a pc, servers can run windows fine. It will be very slow. It's gotta be $50 or less. I wouldn't give it much life left either. It's probably about 10 years old. There are great computers even at $100.
