As many people know I work with technology for a living. For those of you who don't, well I work with technology for a living.
To support that I keep a batch of hardware at home for purposes of playing around with new software solutions that I get my hands on. For a while I had been scaling back more and more and more on the hardware that I keep in house and using virtualization more and more. However it eventually got to the point where I wasn't replacing my hardware at a pace that could keep up with the number of machines dying due to old age.
I was looking around at getting some new gear, but then I got a call from a friend who had some machines that where being disposed of and they where wondering if I was interested in recycling them for them. I figured that I may as well have a look at them, and in the end it turned out that they where a bunch of HP 6000 PRO machines running dual core processors. While these aren't the most powerful pieces of hardware they are enough to run VMWare ESXi and the price was right.
Unfortunately there was only enough memory to get a few machines running properly, but just having to purchase memory is a dammed sight better than having to purchase an entire system.
