I ended up buying the parts for a NAS build today.
It’s going to have these parts: https://pcpartpicker.com/list/LBM74p
Which is slightly different than I said yesterday. I changed to the JONSBO N3 case from the N4. There are a few reasons for the switch.
The N3 allows for 2 more 3.5 inch drives, as well as a single 2.5 inch one. I get to re-use the stock cooler for the CPU, which wouldn’t have fit in the N4 case. There’s more headroom for a GPU, though it won’t fit the 2070 Super that I currently have, which is 7mm too long for the N3.
Ultimately, this case lets me grow the NAS in place for a bit more than the N4 would.
In terms of photo workflow, I’ve started to look at PhotoPrism which seems like it’ll be fine even without a GPU, but still do some automatic indexing and categorizing for me.
