May 3May 3 Hi all, I've been running Unraid on an old OptiPlex connected to a USB drive enclosure. I use it mostly as a media server but I'd like to expand my storage and start tinkering more actively with home automation, backups, adguard/DNS stuff, general homelab experiments. Would also eventually like to be able to access the server remotely but local is fine for now. I'm also profoundly naive about transcoding - whether I need it, whether I'm doing it now, where I'm doing it if I'm doing it.The problem I'm looking to solve at the moment is twofold: I'm aware that the USB connection is less than ideal for a number of reasons, and the bay itself runs hot enough that I've had to set Unraid to spin down the drives when not in use, which is embarrassing.The plan I've landed on:After auditing my existing hardware (I had a spare tower in the basement with a PSU I can reuse), here's the patchwork build I'm considering:PartNotesNot sure how to delete this third columnFractal Design Node 8048× 3.5" native bays, dedicated drive chamber with direct airflowASRock N100MmATX, N100 CPU soldered on, PCIe x16 slot for HBA16GB DDR4 DIMMSingle slot on the N100MLSI 9211-8i (used(?), IT mode)For SATA expansion — N100M only has 2 native ports, so HBA is mandatorySATA cablesEVGA 500W PSUReused from old tower2.5" SATA SSDReused from OptiPlex (cache drive)Existing drives transfer across as-is. Unraid licence stays on its USB stick, so no reinstall needed.Admittedly, I've been doing research above my station about this and I know very little about the compatibility of this hardware - using the HBA expansion, for example. One thing I'm already second-guessing: the N100M only has 2 native SATA ports, which means I'm forced to add an HBA just to connect my 4 existing drives. I've been informed that N5105-based boards often ship with 4-6 native SATA ports and two RAM slots, which would potentially eliminate the HBA requirement and allow more RAM headroom at the cost of a slower CPU (and weaker "Quick Sync", which allegedly has something to do with transcoding). Questions for the community:N100M vs N5105 board - Is the N100 worth the trade-off for a setup like mine (bearing in mind my juvenile level of technical expertise), or would an N5105 board actually be the smarter choice here? Something else entirely?N100M + Unraid compatibility - I've seen one or two reports of instability (hangs/reboots) with this board under Unraid. Is this something I should be concerned about?LSI 9211-8i in IT mode - is this the HBA I want, is there something better/cheaper available now for a European buyer, or is an HBA a bad idea to begin with? Transcoding reality check - I stream mostly to local devices - NVIDIA Shield, phone, laptop. I genuinely don't know if I'm transcoding or direct playing. Is the N100's Quick Sync sufficient for a small household (usually no more than 2 local streams simultaneously but would be nice if it could support more, potentially remotely)?Anything obviously wrong with this plan? Happy to be told I'm missing something before I spend the money.Located in Germany, so European availability matters. Thanks in advance.
