Rotating components like fans and hard drives are what fails. And batteries, look out for RAID controllers with battery backed write cache. Assuming you bought a used several generations old server off lease, by the time the battery dies, you probably can’t buy a replacement. Oh, and power supplies seem to fail.
So fanless is good, SSD is good. I don’t know about latest generation, but traditionally the HP/Compaq DL series rackmount servers are built like tanks, and things like redundant hot swap fans can mitigate the problem with fans failing. Be sure to stock a few spare fan modules and power supplies. IMHO if you are looking for a rackmount server, 2U is more reliable than 1U. Things like fans and power supplies and heatsinks are compromised to fit into the 1U height. Components in a 2U chassis can be a lot more robust. Most of the HP and Dell servers will be very deep, and will need to go in a cabinet or 4 post rack. There are solutions for mounting a deep server in a 2 post rack but they are ugly. If you want regular rackmount, Supermicro has a few short depth chassis servers that can be mounted without a rail kit. I haven’t had any failure problems with Supermicro except a couple with ATOM C2000 LPC clock failures after a couple years and that was Intel’s fault. They aren’t the mechanical thing of beauty inside though that a DL380 is, the mechanical design is just good enough.
