       did some thinking on a local home server/nas devicea tiny or mini pc like the lenovo p330, lenovo thinkcentre m920x, optiplex 7050, etc are good choices power, price and I/O wise. also efficiency.  10W device are reasonable. they cost between 100-200€ roughly 30€ in energy costs per year(for me it is roughly watt*3= yearly energy cost)the issue is: storage. i would like atleast 8tb storage. + 500gb services + 256gb systemthe latter two can be handled with cheap SSDs and is not an issue. backups are enough redundancy for me herethe 8TB are an issue. depending on the number of disks i use mirroring (RAID1), raid-z1 or raid-z2. i decided to go as low as possible for power efficiency. other options will be for future upgrades. one HDD takes roughly 5-10W. so another 15-30€ per year. well more like 15€ because it will idle mostly.1x 8tb backup+ 2x 8TB for mirroringSSDs are faster and more efficient. but expensive.  very. 800-1000€ for 8TB. so suddenly we are above 2500€ total cost. not an option. HDD it is. RPM: 5400 vs 7200, I wanna reduce yearly costs. 5400 is fast enough i think (80Mbyte/s)So 3x 5400 RPM HDD it is1Gbit Ethernet is fast enough as long as i dont add anything else.so 3x8tb .... cheapest one i find new:137,94€, so total roughly 400€ used/refurbished (scary): 120€ for enterprise refurbished hdds, still 360€or 5x 84€ (for more redundancy) 6TB SAS and a SAS controller for 40€ and being sure this works with the mini pc i will buy.TLDR: DISKS are hecking expensive.

       @grillchen Only really necessary if you want to build something more fail-safeAch und definitiv die langsamen platten nehmen!

       @SuicideSchaf mmhh überlege ob ich lieber ein backup mehr hab oder mehr redundancy. aber glaube werde das kostenmässig eh langsam angehen. gerade wichtigere andere extra ausgaben und lass dann andere ausgaben gerne erstmal ruhen

       @grillchen ja in jedem die langsameren platten als NAS reichen dieEs komnt aber eben auch noch anderer Punkt dazu die großen Platten wenn die ausfallen ist der Datenverlust höher. Im selben Augenblick.

       @SuicideSchaf also thinking about a classic motherboard + low power cpu + efficient power supply build.  i dont care about a case at all since i can build stuff myself (alu crafting and 3d printing
