Notes on Components

Motherboard

Ideal for low-power systems such as N5105 or N100 systems.
BKHD-1264-NAS (N100)           
CW-ADLN-NAS (N100/N305)  <--- rear i/o specifically designed for this one
BKHD-N5100-NAS-I226 (N5105)    

Case design is such that the maximum height of any components on the motherboard (including CPU cooler) which sit under the HDD caddy must be less than half the I/O shield (ie. thinITX).

By getting the CW-ADLN-NAS motherboard with a Jonsbo H400S White, the fan can be removed leaving the CPU passively cooled.

Fasteners

The HDD shoulder screws used have the following specifications:

• Cap diameter: 10.30 mm
• Thread diameter: 3.4 mm
• Unthreaded polished rod piece diameter: 4.53 mm
• Total length: 11.3 mm
• Lid thickness: 1.47 mm
• Polished rod length: 4.83 mm
• Thread length: 5 mm
