Overclockersclub received a tour at Mushkin, you can check it out over here.
"There is a saying that big things come in small packages and this suits Mushkin to a tee. They may not have hundreds of employees or dozens of offices, but they sure do damn well with what they have. I spent two days in the offices watching, asking questions and learning how they do business. I was amazed at the overall moral of the company and how everyone smiles and just loves their job. One thing that stood out to me was when they got a big order, and everyone ran to the back to help out and pack orders. When I say everyone, I mean everyone - sales people, tech guys - even the president of the company."
