I have a Corsair Professional Series 80 PLUS Gold (AX850) with cables

The case has 2 80 fans at the rear.

It is only built for 4 SATA devices.

I have 2 Seagate Dell enterprise plus ST4000NM0023 4 TB SAS 2 3.5 in Enterprise Drives

I have 2 Samsung 970 EVO Plus NVMe M.2 SSD 1TB

Plan to use the NVME in RAID 1 if possible

I only have 1 M.2 slot so I may use two SSDs for Raid 1
