From the rear we see that the system is powered by a Flex-ATX style power supply (350w Bronze rated). It also looks like a custom motherboard has been developed for this system. It’ll be interesting to see deeper inside this computer.
That PSU is NOT FlexATX, it is 1U! FlexATX is ~80mm wide, 1U ~100. FlexATX wouldn't fit a 40mm fan, C14 inlet and a toggle switch on the back. You might want to correct that in the article. The Hadron used a 1U PSU as well.
I think it is funny how MSI goes full berserk on custom components like the CPU cooler, the riser (which seems to be of custom height) and mainboard to get down to 10L while they could've easily done that with regular components. They even used a tray-loading ODD with a custom faceplate instead of going for a slot-loader, couldn't tell you why.
Also, wasn't the name already confirmed to be M1? Did they change that or did we just overreact upon the name so similar to the NCASE M1?
Didn't know that this was going to be a pre-built system, either, I thought it would be a case. Maybe they didn't want bad reviews or feedback from people complaining about insufficient component support.
That was indeed an extremely cool build, but I think people will be less angry about a major company getting ideas from a one-off build than getting ideas from an independent competitor.
