Computer with readily accessible motherboard

A tower computer comprising:

• a housing comprising:
• a laterally and longitudinally extending base portion;
• a laterally and longitudinally extending top portion;
• a vertically and laterally extending front portion extending between said top and base portions;
• a vertically and laterally extending rear portion extending between said top and said base portions;
• a vertically and longitudinally extending first lateral side portion having a height and a length and having an inside surface and an outside surface and extending between said top and base portions and between said front and rear portions;
• a vertically and longitudinally extending second lateral side portion having a height and a length and having an inside surface and an outside surface and extending between said top and base portions and between said front and rear portions;
• a generally flat motherboard substrate having on one side a first flat surface upon which electronic components are mounted and having on an opposite side a second flat surface, said motherboard substrate having a length substantially the same as said length of said first lateral side portion and being mounted with said inside surface of said first lateral side portion positioned in fixed, next adjacent relationship with said second flat surface of said motherboard substrate;
• said second lateral side portion comprising an opening therein positioned opposite said motherboard substrate and being substantially coextensive therewith and a closure member displaceably, openably, and closeably associated with said opening;
• a motherboard chamber being defined by a space positioned between said motherboard substrate first flat surface and said opening, said motherboard chamber being substantially free of computer components other than components mounted on said motherboard substrate, said motherboard substrate and components mounted thereon being readily-accessible through said opening.
