I am cleaning my apartment and have a piece we are looking to move out. It is the Ikea PS cabinet in silver.
http://www.ikea.com/us/en/catalog/products/80100190/ (it now only comes in red and white at Ikea)
The piece is fully functional and stores a lot. The keys work as well.
The top is slightly messed up though. We bought it used and there were marks on the top. Adding 3 years of us using it and the marks got worse. It you either put stuff on it (like we do) or whatever it will look good.
We are looking for $20 or best offer. We are on the 3rd floor and can help you carry it down, but you'll need to help too. It is lightweight but big.
