I've been thinking recently about all the cool things you could do with the keyboard trays that you see on some desks (store paper there, or your scanner...) but I don't have one of those.
However, I can get one, and so can you:
$9.99 Summera Pull out keyboard tray
You install this on the bottom of any thick, drillable surface (it says you need 3/4" depth) and then you can a cool sliding shelf.
I wonder if you could even put it in a cabinet and basically double your shelf space.
I guess you would have to store flat things, but spaghetti packages are pretty flat.
$6.99 Signum cable outlet kit
This is pretty neat. It's a circular saw drill bit that screws onto your home drill (you have one, right?) and cuts out a nice circle which just happens to be the size of the 3 outlet thingies it comes with!
See? You can make your desk or table into something that can hold cords.
$10 Signum Cord manager
Here is another little device that can hold your cords and chargers under the table so they are out of the way.
$9.99 Kvissle Cable box
If your cables have to be out, at least they can be hidden stylishly inside this box
