Power for the backplane is delivered via four 4-pin molex connectors. The data connectors are four SFF-8643 ports. I purchased a used LSI 9300-16i for the HBA (which has SFF-8643 ports also), so that I’d have the simplest cabling and not have to deal with a second HBA or expander. I could have gone with a 92xx series solution, as I currently just have spinning SATA disks and don’t need 12 gbps, but will probably add SAS disks and SSDs in the future. I’m running TrueNAS Scale with a few VMs on the HL15. I realize proxmox is more powerful for virtualization, but I’m more comfortable in TrueNAS right now and my use case was storage-first/vm-second. I’m learning proxmox on a different system. The backplane and backplane w/ PSU chassis options do come with fans installed. Specifically CoolerGuys 120X120X25MM 3-Pin Medium Speed. You can review [this thread](https://forum.45homelab.com/t/best-fan-upgrades/105/2) for all about fans and fan options. I’m not sure the Noctua D15 will fit in the case, at least not with 140mm fans. See [here](https://forum.45homelab.com/t/hl15-max-cpu-cooler-height/364/12). Other than that your build seems fine to me. For 10g are you planning to use SFP+/DAC or RJ45 connectors and Cat6 cable? I think 10G networking has become pretty much commodity now. TrueNAS/Linux should support most NICs. --- _[View the full topic](https://forum.45homelab.com/t/hl15-all-ssd-power-supply-requirements/990)._
