thanks for the feedback, as for upgrades I was thinking about a better processor but the Dell T20 is an old model got it at a good price on eBay, I was thinking 4 x 8TB drives but still debating it. I am new to using unraid, so I want to play around with this build learn as much as possible then think about my next built version. I do want to use it for my media server and rip as many UHD Blur ray movie I can get my hands on; and transcode lower quality movies to 4K versions I do travel a lot so I would like to access my server remotely; and on my mobile device, also use it and setup my home security system, run a few windows VM for testing what your thoughts on pass-through devices?
