Claim:
A rack system for containing electronic and/or electrical equipment, comprising: a. a rectangular base frame having four horizontal support members each extending along a longitudinal axis; b. a rectangular top frame having four horizontal support members each extending along a longitudinal axis; wherein each horizontal support member of said base frame and said top frame is made from an elongated sheet material extending along a longitudinal axis by bending the sheet material about an axis parallel to said longitudinal axis to form two step-like side peripheral surfaces, attaching two side elongated edges of said elongated sheet material together; c. four elongated vertical support members each extending along a longitudinal axis between and joined to two associated comers of said rectangular base frame and said rectangular top frame, wherein each said elongated vertical support member is made from an elongated sheet material extending along a longitudinal axis by bending said sheet material about an axis parallel to said longitudinal axis of said sheet material to form at least three elongated sections wherein adjacent sections are substantially perpendicular to each other; d. panels mounted to surface planes of the rack system, wherein said panels include a top panel attached to said top frame, wherein said top panel includes tabs extending outwardly from a first edge of said top panel, and said horizontal support member which is associated with said first edge defines slots facing and for receiving said tabs, wherein a second edge of said top panel opposite to said first edge includes a latch for locking said second edge to an associated horizontal member.
