Yes, ECC memory. If used, then CPU also needs to be able to support it. Then there’s number of cores, unless you specifically need high single-core performance. Efficient and reliable PSU, low power-consumption, lots of memory, redundancy for storage. Stuff like that.
None of which are essential, BTW. Any working PC can be made into a server regardless of its hardware.
All server really is is just another PC that’s been built with a different purpose in mind. The rest is software configuration. They need to be reliable, scalable, and cost you as little as possible to upkeep.
