A computer is disclosed having a power supply assembly that may be rotated into a first position for operating the computer, rotated into a second position for servicing components within the computer, or removed from the computer quickly and easily. The power supply assembly is mounted to a chassis via first and second pivot pins that define an axis of rotation and engage first and second bearing surfaces. The first pivot pin may be disengaged from the first bearing surface without removing a fastener. In one embodinent, the first pivot pin is disengaged from the first bearing surface by relative movement between the first pivot pin and the first bearing surface along the axis of rotation. In another embodiment, the first pivot pin is disengaged from the first bearing surface by passing it through a slot in the bearing surface orthogonal to the axis of rotation. A support member mechanically coupled to the chassis at a hinge is folded downward when the power supply assembly is in the operating position and extended upward to support the assembly when it is in the service position. A power coupling is located within a protrusion on the power supply assembly that aligns with a power coupling hole in the chassis when the assembly is in the operating position. A conductive gasket around the protrusion engages a conductive shroud around the power coupling hole to reduce leakage of electromagnetic energy from the enclosure.

Rotatable removable computer power supply

An actively cooled daughterboard system. One more daughterboards are mounted in parallel rows on a motherboard. Each daughterboard is oriented substantially perpendicular to the motherboard, but may optionally be mounted at an oblique angle relative to the motherboard. Each daughterboard has a low-profile thermally-efficient heatsink mounted thereon. A fan shroud partially covers the daughterboards, but has openings in its sides for directing air flow through plural fins on the heatsinks and through a fan mounted to the top of the fan shroud. The inventive daughterboard system enables multiple high heat dissipating daughterboards to be placed closer together than the daughterboard systems of the prior art while still keeping the daughterboards adequately cooled. Moreover, because only a single fan is used to cool all of the daughterboards under the shroud, noise and expense are reduced relative to prior art systems that employed one or more fans per daughterboard.

Actively cooled daughterboard system

A heatsink for use with an actively cooled daughterboard system. Plural transverse fins are integrally formed with a base portion. The fins are radially displaced from one another. The base portion includes a central portion that is thicker than the end portions. The thickness of the base portion and the profile formed by the outer ends of the fins vary according to radii. The inner radius associated with the central fins is shorter than the inner radius associated with the endmost fins.
