I had a similar network appliance "nest". I got a rolling kitchen island from IKEA because it has shelves that encourage ventilation and it also fit my printer, UPC, and HTPC/server. Now I have one network appliance cart. Everything is always a few inches off of the floor. All the cords are contained and tied off where necessary to keep the cart's contents from spilling out in the way. When it's time to clean around it, it can be wheeled away from the wall or corner. The only cords still connected to the wall are one for power and one for Internet. I can even disconnect it entirely from the wall briefly without too much fuss, just a short time without internet but with the wifi intact.
The cart would be overkill in your case, but the idea of it would still have value. You could probably fit everything you've got into an empty milk crate. That crate could be on wheels and most crates are pretty well ventilated.
Key lime juice also makes for a very interesting margarita.
