I just bought a desk that has ample room for my tower, so now I am selling my adjustable CPU cart. It is silver and has 4 nuts that allow you to adjust the width 7"- 10.5". Has casters, will roll easily if needed. This unit will raise your tower 3" off the ground and protect it from water and will allow air flow underneath.
