I've had the blog running in a virtual machine for a while since the power supply on my server blew, but that's it back onto dedicated hardware now..
In fact it's a nice little debian server using a Buffalo Linkstation Pro reflashed with FreeLink.
Pretty good deal as you get a perfectly good linux server based on a 130 pound piece of hardware. I've got two of them running now, one as a web server and one as a file/print server. There a lot smaller an quieter than running full-tower cases in the office!
