Ellninerr

Ellninerr is a friend of Pintsize. They and another unnamed AnthroPC meet in a coffee shop. Ell's owner is into modding AnthroPC chassis.
In the newspost under the only comic Ellninerr appears in, Jeph mentions PC modding.
Transcription on http://www.ohnorobot.com also lists the unnamed yellow AnthroPC in as Ellninerr. It's quite possible, as the second unnamed pink AnthroPC from this comic also appears with Ellninerr in and Ell's owner is known for painting the chassis.
