I also have a sheeva plug as my server, but if i did it over I would choose to grab an mac mini. My big jump to the sheeva was the power usage, but then I found out the mini only uses 12W! Along with the 12W you get a x86, with hd, cd drive, wifi, etc on a box that I can easily load linux (upgrading the sheeva's kernel isn't the easiest...) and in a few years when done with it I can easily sell the mini unlike the sheeva.
