Administrative servitor 'Murphy'

[Holiad]

Hi there people. Been awhile, but I thought I'd post up a few pictures of the NPC I made for the 2015 IGT, an administrative servitor I've tagged with the name Murphy. Yes, after that Murphy, since I can't help but notice a striking similarity in their organic components. Mostly harmless, but capable of great annoyance, as Marcoskoll's stormtrooper sergeant discovered when an attempt to sneak up on the rival inquisitor was foiled by a loud enquiry of "Do you require assistance, citizen?"
Anyone care to try and identify all the pieces I put on it? (Disclaimer-I'm not certain that *I* can.)

Kai was not impressed.

The attendees (myself included) were rather more so! I don't think it came up before, but it was this gent who earned second place in the IGT P&M round, with an 8/10 score (just half a point behind Van Helser's Khornate daemonhost).

Nice little fella here (those parts are alarmingly familiar for an eye used to scrutinize tainted artifacts), and that personal history is quite entertaining 
What are the chaos plasmas' new designation?

Straight out of some 40k artwork there, reminds me of Malachi at the end of the redeemer comics
