Chiming in because I think I'm following a similar path, and I actually bought the chassis from the ebay seller linked above. Here is what I settled on, most of which will be on my doorstep in the next few days. I never declared an official budget, but did enough research to convince myself I wasn't paying top dollar. Would like to get this done sooner rather than later to address some issues with current computers, so I wasn't willing to wait for deals on every last part. Already have HDDs, so all in I'm around $895 for a box that will someday run sage, plex, crashplan, and unifi dockers, 2 Windows VMs for sure, NAS, and whatever else tickles my fancy. It will replace 3 other computers, a daily driver in the kitchen, the sage server, and a WHS box that currently is NAS and backs up the sage box.2x Xeon e5-2660 v2 CPUs, 10 cores and 2.2ghz each- ebay seller ESISO $270SuperMicro x9dri-LNF4+ and 32gb ECC- Mrrackables $325 (very good experience with a phone in order because I had some questions. Guy was even willing to share some thoughts on dumb questions that had nothing to do with what I was buying. Highly recommend)SuperMicro 3U SC835BTQ-R1K28B- 8 hotswap bays, 7 full size expansion slots, 2x 1280 watt PSUs- CSE-SAS-833TQ backplane- ebay $300 incl shipping at 57lbs (might sell off one of the PSUs if its not required, also no idea what a backplane even does, thought i would be connecting SATA straight to the mobo, so maybe i can sell that too. I'm sure this will sound like a thousand hair dryers, but it can be modded plus will be in a basement dungeon anyway)
