The Mini comes with an internal PSU, though. All these mini PCs come with external PSUs, some hilariously large at over half the size of the PC itself.
This is true about it being an external PSU, but it is nowhere near 1/2 the size of the computer.
I have one because I was able to get an i5 that was passively cooled, so great for a Plex server that's second hand for only £100. The PSU is more like 1/8th, maybe smaller.
I happen to own a Lenovo Thinkcentre. The PSU is perhaps 1/3 the volume of the computer itself, which I think is crazy for a computer with a mobile chip inside.
I know that some Intel NUCs have monstrous PSUs [0], which I think should constitute false advertising regarding the actual size of the computers.
Fair enough, if I had got that Intel one I would probably have a similar opinion. The power brick I have is about the size of the small Lenovo travel power supplies, maybe about 25% of that Intel one, at a guess without seeing it in person.
It's definitely smaller than 1/3 the volume of the unit unless I have a incredibly small form factor rather than an ultra small form factor unit? But I don't think so. It is very small.
