@tomahawkeer I've got a couple of 8 & 14 drive miners. 10 Drive has an LSI SAS Controller to hook up the mining drives, a PCIe SSD and the OS SSD off the system SATA ports. It's a 4 Core/4 Thread Xeon @ 1.8 GHz. The 14 drive unit combines 6 on board SATA ports and a SAS/SATA Controller - don't recall exactly which one currently. 10 * 3.5" Drives in the chassis 3.5" slots, 4 * 2.5" in a 5.25" to 4 * 2.5" drive bay.
Chassis is: Norco RPC 470
Not sure of power supply off hand, but it had 8/9 SATA power connectors, + Sata Power splitter: Rosewill RCS-302
Got any questions - ask.
