Bitcoin Mining on Office Network I'm a bitcoin novice and i've read a bit about mining. It got me thinking that I could setup our office network to min bitcoin (obviously with permission)

We have a centos linux server which is on 24/7/365 and we have 6 windows 7 machines which are on 8 hours a day during a working week when staff are in working.

Is it possible to setup the linux server to mine bitcoins continuously with very low effect to the server's load and the same with all the windows 7 machines? What sort of mining software would be idea for the setup.
CPU and GPU mining costs more in electricity than it rewards in BTC at the moment.
You need special equipment with ASIC chips to mine at a profit.
These chips are designed to perform many hashes at low power consumption.

I suggest you ask your boss if he agrees with the negative efficiency of your current setup.
