A dash means the card does not list that interface.
Shortlist / one anchor, four cards
The four-LAN board, then the rest.
PNM-5210 has four LAN; the rest share two.
Trade-off / 120 × 120 mm
The fanless middle keeps the ports.
No x16/x4 slot. Port count remains: four LAN, five COM, dual M.2.
2.5-inch is lower power; NUC adds Type-C and higher CPU tiers.
True-scale outline / 0.5 px per mm
120 × 120 mm against its neighbours.
0.5 px/mm; not for drilling.

FAQ / envelope decisions
Three questions that decide the envelope.
Is a 3.5-inch board a drop-in for another vendor's 3.5-inch board?
No. A size class, not a mounting standard; check holes and I/O on the drawing.
When does the next size up pay for itself?
When you need an x16/x4 slot, a socketed 65 W CPU, or more than four LAN.
Which models have a spec card on file?
All five on file.
