Hello I currently run a DS410J and a DS916+. I am looking to build a 12 bay xpenology box. I am looking at getting this case. https://www.amazon.com/Rosewill-Rackmount-Computer-Pre-Installed-RSV-L4000/dp/B0091IZ1ZG/ref=sr_1_8?keywords=rosewill&qid=1563957761&s=gateway&sr=8-8&th=1 or something similar. After that I am confused on what motherboard, cpu, sas controller to get. Any guidance would be greatly appreciated. The main use of this box is for a plex media server with direct play. Thanks for your help!
