There's some seriously impressive and creative rigs here! I'm on the lower-end of specs (trying to stay on a budget until I get the hang of things and establish what my actual needs are), but things have been going smoothly so far! Hoping to upgrade to a Jonsbo case one day and fill it with hand-me-down hardware from my gaming rig. Bought the following off FB marketplace for about $125.
-Case: HP P600 (holds up to x5 3.5" HDDs with some minor modifications to add hot-swappable slots on the front and an additional fans in the front/side.
-CPU: Ryzen 2600
-RAM: 16GB
-Mobo: Asrock a320m-hdv micro ATX
-GPU: Nvidia GTX970 (considering removing to reduce idle power draw - don't think this is useful for anything other than a video output)
-Boot drive: random 128 GB M.2 SSD (not sure of brand.... hoping HexOS adds the ability to backup the configs sooner than later...)
-PSU: Phanteks Revolt 1000W 80 Plus Platinum (laughably overkill.... computer came with a sketchy EVGA white PSU that I replaced ASAP - this is a hand-me-down from the gaming rig.)
-Storage: (x3) 10 TB shucked HDDs (two seagate barracudas and one WD). Looking forward to expanding this one day soon!
Hopefully the below specs help assure others just how easy it is to run this software. I'll definitely need to upgrade my memory and CPU if I start loading too many apps on it, but this runs immich just fine for now with about 50% of RAM to spare!
