Estropelic

Coming from a Truenas build that's over ten years old. It's served me well for the years it's been active. I'm getting disk errors and I need to move over to a new server soon as I'm getting all sorts of new errors out of nowhere. Current configuration: 1X ASRock C2750D4I Mini ITX Server Motherboard FCBGA1283 DDR3 1600 / 1333 1 x Crucial 16GB (2 x 8GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3L 1600 (PC3L 12800) Server Memory Model ... 6X WD Red 2TB NAS Hard Disk Drive - 5400 RPM Class SATA 6Gb/s 64MB Cache 3.5 Inch - WD20EFRX I had a two disk failover with 9tb usable space I believe. As much as I loved the small form factor of the node304, I'm ready to build something larger and that I can expand in the future without having to worry about cable management. I'd like to double my storage while I'm at it and use the box mainly for storing home documents, Plex streaming for the family 3 streams if necessary, and possibly a VM or two. Are there any guides I should use to research the build? I took a peek at pcpartspicker and many of the guides are not current or not mentioned as suggested builds for unraid. Edit: I'm going to go with a Meshify 2 XL and would like to get my 9tb pool back online but would also like to expand out to a good amount of tb 23+. Also want to run ZFS.
