How would you change HP's MediaSmart Server ex485 / ex487?

Now that you've had a few months a stream all manners of media throughout your home and backup your small cadre of computers via one of HP's new MediaSmart Servers, we're interested in seeing just how you'd change this bad boy. HP popped in a faster processor and a bit more RAM in order to make sure these, um, actually worked as advertised, but we're certain even that hasn't satisfied the hardcore critics in attendance. Have you been totally satisfied with your ex485 / ex487? Has the server handled all the Windows Home Server functions with ease? Are you noticing any lag? Are you happy with the file support, heat output and overall styling? Feel free to rant uncontrollably in comments below -- just keep it under control.
