An instrumentation rack (10) includes a rectangular base frame (12) and a slanted support structure (13) having a pair of bent transverse braces (54). The bent braces (54) can be formed in a variety of heights and with a range of medial bends (70) to provide a variety of shapes for the instrumentation rack (10). A pair of straight mounting rails (76) are longitudinally aligned along a slant angle (72) preferably determined by the angle of medial bends (70). The slant of the mounting rails (76) permits the face plates, including controls and monitors, of equipment to be angled advantageously for operator comfort, access, and visibility. This angled arrangement permits equipment to be ergonomically stored and operated below desk level.
