I ordered the audio rack to use as a media room rack. It arrived promptly and was very well packaged. This manufacturer has the clearest assembly procedures of any furniture I have bought online. Each piece of furniture and hardware was separately labeled. Even the smallest piece of hardware was in its own bag with a label on it. The instructions were clear and concise. After I put it together, I drilled a matrix of small ventilation holes in the bottom (base) shelf. I also installed a small light computer type exhaust fan at the top rear to keep the air moving and venting out the back. I did not need to drill ventilation holes on any of the top shelves since they sit an inch or more behind the glass door so air can flow naturally. I have my Denon receiver, a stereo amplifier, DVD player and satellite receiver in the cabinet, and the heat is not an issue at all. The cabinet looks good.
