I've put the top and bottom lid on my new sub-$400 all-in-one dual-core LCD PC and mounted an 802.11 b/g USB adapter to it so I can use the computer anywhere in the house. To keep the chassis cool, I drilled 5 large holes on the top board. I am still waiting for my female USB socket connectors that hook up to the USB leads on the motherboard so I've temporarily used one the venting holes to mount the USB Wi-Fi adapter. I also need to paint the thing black to match the color of the LCD and sand some things down. [See gallery, A computer's place is in the kitchen, for larger photos.]
The AIO computer is sitting on the corner of my kitchen dining table and there are no bulky ATX towers sitting on the floor or table.
This particular power strip is a bit bulky so I'm looking forward to finding something thinner that I can bolt to the bottom of the PC chassis. Having the extra power sockets right there on the computer is really nice to have.
When the computer isn't being used or if it's being used as a movie playback device, I can tuck the mouse and keyboard away taking up less room than a laptop sitting on the table.
To put this in to proper perspective, here's the entire kitchen table with the AIO computer sitting at the edge of the table. It hardly takes any room and the table is wide open for eating. I finally had the kids eating at the kitchen table for once since I had a movie playing. Once I get an HDTV ATSC USB tuner dongle, this will also act as an HDTV with PVR capability along with wireless connectivity to a DVD library.
This is what the back looks like. It will be a lot less noticeable once it's sanded and painted all black.

Update 11/30/2007 - I've bolted a slimmer power strip to the bottom of the wood box and it's a lot cleaner since I no longer have a loose power strip to worry about. It gives me extra AC ports for things like speakers or anything else that needs power.
