160 GB hard drive. Wasn't Serial ATA, but I don't mind. This is fairly important; it means I can move my 60gb drive into the server, which means I can toss Debian for Gentoo and have a fully operational system once more. w00t. (No thanks to my users...)
On a somewhat related note, I discovered today that on its own, duct tape does not make good wrapping paper, especially because you need two layers to make sure it doesn't stick to the present. OTOH, duct tape combined with another material, such as a small box or several pieces of scratch paper, does work alright.
Y'know, just in case anybody else has that idea.
