I'm pretty sure that the government has technology way better than the public's. Since Pintsize has government chassis, he's probably cutting edge as of right now.
Remember, the government issue hardware was bought (accidentally; Marten thought he was buying standard hardware) because Pintsize ruined his old hardware with cake. (
#58) He says the cake was "worth the massive motherboard damage" so he probably needed all new hardware. Considering that, he probably isn't too outdated yet; remember the last time he threw a little robot party, most of them looked just like him but in different colors. I think the Linux AnthroPC is more likely ot be old hardware, because its chassis is more square and it has to have a neckbeard/heatsink.
Of course if they use a standard form factor (equivalent to real-world ATX), all this speculation goes out the window.
Goddammit now I feel like one of those nerds who tries to piece together how the ships from Battlestar Galactica and all their subsystems work I HOPE YOU"RE HAPPY > : C
