Starter kits – This was the goldilocks zone; not too sparse, and not too expensive. These listings would come with a processor or two installed with heatsinks, a couple of drive caddies (required for adding hard drives), ample (and matching) memory, and seller guarantees of the servers working when they shipped. Sure, they didn’t come with the beefiest RAID controllers, the most RAM, or any storage, but that’s all stuff that can be had fairly cheaply and with the specifications I wanted. This was ultimately the “style” of listing I chose when I made my purchase.
