A spacer formation cell usable in configuration of a window assembly, wherein the cell includes a plurality of stages through which a spacer work piece is routed, and the stages include a holding stage, a cutting stage, a bending stage, and a connecting stage. The stages can be arranged in interlinked configuration, enabling spacers to be fabricated in a direct and time-efficient manner. The stages can be interlinked to form a framework, forming an exterior enclosure for the stages of the cell, and enabling at least of the majority of the cell's operations to be readily overseen by an operator from single vantage points around the cell. The configuration of the formation cell enables a wide variety of spacer types and/or sizes to be readily processed, with such processing to be readily alternated.
