At the same time, I was running a home router without any HDD on LRP, Linux Router Project, which was a distribution from Swansea Linux, and was a floppy image, that decompressed into RAM, and then chrood to the RAM image. Really nifty, except for the 486 machine had a Pentium Overdrive, which was vulnerable to F00F, and we got owned... only to reboot again, and back to our normal image.

Since it had no hard disk, and no monitor, it was quiet, and used little power.
