You can't compare the wattage on a BFL with an Avalon. An Avalon is a self-contained mining device. Add in the wattage for the laptop and the BFL is less efficient than an Avalon! ROFLMAO.
Except it's not. When you add in even 100w for a laptop, then plug in 10 BFL singles, suddenly that laptop only uses an extra 10w per single. There's no point to have 10 different hard drives, 10 wifi modules, etc. all of that can be taken care of with 1 mini computer (~$150 for a new one, running at ~50w with either windows or Linux).
Also, of you've only got 1 unit, run it off a RPi, and that only consumes, what, 10w or something rediculus? You could probably find a way to mount the Pi inside the jalapeño, and cut a hole out the back for Ethernet & additional power cord. Would certainly be an interesting project.
