In case someone stumbles on this post and is interested in the build, so they know what works

• Intel I-7 8700 with a Random Cooler (Be aware of height clearance for coolers)
• 32gb ram
• MSI Z730M motherboard
• 32gb ram
• Rosewill RSV-L4500U
• Dell H730 RAID Controller
• Adaptec 2283400-R AEC 82885T SAS Expander
• 650w PSU with three SATA power cables, each cable has a breakout cable powering 2-3 drives. I would highly recommend a PSU with four sata power cables if possible, but I also believe the RSV has some weird clearance restrictions with PSU length
• Intel X520-DA2 10gb SFP Network Card

The Dell H730 has the ability to enable HBA mode in the settings menu so no flashing is needed, and the card works flawlessly (so far) with the Adaptec. This config also restricts you from using a GPU and the Expander needs powered via molex. I’m also happy to answer any questions about the build
