Planned Switch to Unraid from Truenas

[Menaxerius]

Hi,
I'm currently on Truenas Scale, with one pool with two arrays 10x 10 tb and 10x 8 tb each in an z2 configuration. Mainly used as Plex & Arr Server. Storage is about to be 80% full. So I'm planning to do a full replacement of the System. I'm located in Switzerland, and power consumption is a bit of a concern, so thats something I want to factor in aswell, but isn't the main focus. 

Currently I'm on a Threadripper 1950X, with 64 GB Ram. 

Due to Pricing, I'm currently looking at Drives from Serverpartdeals, as their refurbished drives seem to be a great value, but I'm open for pretty much everything. 

My Plex Library is huge, so thats my main focus, as usability of Plex with metadata, previews and so on:


My Budget isn't that limited, but I appreciate a good value. 

What would you get? And what configuration would you use? 

I have a bunch of 24 Bay 4 U Cases around, and will like use one of them again. 

Open for discussion. But I'm new to Unraid, but happy to learn. 

Thanks in advance

Mena
