More on that purple soon 
In the mean time...another mini update:
The Metis has some questionable design choices when it comes to air flow and cooling
The side panel vent is actually behind the motherboard tray, I can understand this was likely cost driven but the reality is that those vent holes are largely useless behind the motherboard tray. So I flipped the side panel to put the vent behind the other end of the tray:

'But Dan, that's even worse!
' - It sure is!
But I like to think there's nothing an angle grinder can't at least contribute considerably to fixing....

This vent will now be at the front of the case in the cavity between the PSU and side panel, I hope *crosses fingers* that this will provide another avenue for air to escape the case so I'm not only relying on the PSU exhaust fan to expel hot air.
