Overall (mm): length 50.0, width 38.0, height 20.9
- Datum: body centre; bottom (screw-hole face) at 0, label face at 20.9 (nominal 21). x is measured from the −x end as on the drawing.
- Body 50.0 × 38.0 × 20.9. Four M2 self-tapping screw holes in the bottom on a 45.0 × 33.0 pattern, modelled Ø2.0 × 4.0 deep (depth not given).
- Air face (one long side): a row of four Ø2.5 inlet openings 2.45 below the top, the first 6.0 from the −x end, 4.0 apart; fan outlet grille R6 to R9 centred 35.8 from the −x end at mid-height.
- Connector face (the other long side): opening 17.0 wide × 4.9 tall, its right end 5.5 from the +x end, at mid-height.
- Not modelled: the shell corner radii, the ribs of the fan grille and the interior.
- Dimensions are exact nominal (true size), no tolerance added.
