Mounting bracket for use with a computer and method of assembling a computer

A method for assembling a stacked single board computer that includes a top printed circuit board (PCB) and a bottom printed circuit board (PCB), the top PCB including at least one mezzanine card, said method comprising:

• coupling the mezzanine card to the top PCB;
• positioning a retaining rail along only a first side surface of the mezzanine card, the retaining rail including a main body having a first arm formed at a first end of the main body and a second arm formed at a second end of the main body;
• inserting the first arm into the top PCB such that a notch formed in the first arm interferes with a corresponding slot formed in the top PCB, such that said first arm is substantially perpendicular to a top surface of the top PCB;
• and
• positioning at least one top rail of the retaining rail with respect to a top surface of the mezzanine card,
• wherein said notch is configured to engage an upper surface and a lower surface of said top PCB.

A stacked single board computer comprising:

• a first printed circuit board (PCB) and a second printed circuit board (PCB) positioned adjacent said first PCB, said first PCB comprising at least one mezzanine card that is secured by at least one retaining rail comprising:
• a main body comprising a first end, a second end opposite said first end, a first side surface, and a second side surface opposite said first side surface, said main body sized to be positioned along only one side surface of said mezzanine card, one of said first side surface and said second side surface contacting said side surface of said mezzanine card to facilitate securing said side surface of said mezzanine card with respect to said first PCB;
• a first arm formed at said first end;
• a second arm formed at said second end;
• and
• at least one top rail coupled to said top surface, said at least one top rail configured to secure a top surface of said mezzanine card with respect to said first PCB, wherein said first arm and said second arm are configured to be positioned in a substantially perpendicular direction relative to a top surface of said first PCB,
• wherein at least one of said first arm and said second arm further comprises a notch configured to engage an upper surface and a lower surface of said first PCB.
