Step 1: Let's start out by creating a new file. I used a 400x400 pixels canvas set at 72dpi, and I filled my background with a black color. Now create a new layer set and name it 'Hosting Rack Design'. Then create a new layer and draw a rectangle with 144x273 px dimensions and #AFAFAF color shade.
Step 2: Under Layer Style(Layer > Layer Style) add an Inner Shadow, Inner Glow and Gradient Overlay blending options to your gray rectangle layer.
Step 3: Create another new layer and draw a rectangle with 140x11 px dimensions and #AFAFAF color shade located on top of the body of the hosting rack.
Step 4: Under Layer Style(Layer > Layer Style) add an Inner Shadow and Gradient Overlay blending options to your smaller rectangle layer.
Step 5: Now make another new layer and draw a black rectangle with 130x42 px dimensions.
Step 6: Under Layer Style(Layer > Layer Style) add a Pattern Overlay blending option to your black rectangle layer. Then set the layers blending mode to Soft Light.
Step 7: Just below the screen like design draw a rectangle with 140x11 px dimensions in a new layer.
Step 8: Under Layer Style(Layer > Layer Style) add a Gradient Overlay and Stroke blending options to your gray rectangle layer from the last step.
Step 9: Add more rectangle structure design below the original, about 4 more designs.
Step 10: Create a new layer, between two of your rectangle structures set up on the hosting rack add a rectangle with 124x4 px dimensions and #00D2FF color shade.
Step 11: Under Layer Style(Layer > Layer Style) add an Inner Glow and Gradient Overlay blending options to your neon colored rectangle layer.
Step 12: Add the same blue rectangle design as shown below.
Step 13: Finish it off with a blue rectangle design on top of the hosting rack.
Results: Hosting Rack Design.
