My storage solution for computer-related accessories: 4 x HELMER 1 x ÄTRAN 2 x RILL (wheels) Painted all HELMERs black in a special furnace. (at the time only red, white and grey were available). Attached everything together using screws, nuts and bolts. The Ätran cabinet is attached to the side of the HELMER stack. Wheels are much sturdier than the regular ones HELMER is shipped with.
