This thing is a server rack monster. It's thick, heavy-duty steel and I'm sure there will be no problem holding the 200+ pounds it's rated for. I currently have a 1U server plus a 2U storage array and a UPS. The UPS will likely be upgraded with an extra battery and I'm sure the rack will handle the extra weight with no problem. The wheels are strong enough. They appear to be slightly rubberized and not just pure plastic. The movement of the rack is quite quiet, especially when loading equipment (I greased the wheels a bit because they creaked a bit after assembly). In general I am very satisfied. It comes with lots of hardware for mounting hardware. I will most likely buy again if the need arises.
