Thats a problem I have with my Mindset computers. You have to put them
on switched power strips, otherwise even when off, you can put you hand
along the side of the case and it feels physically warm as the p/s is
still quite active.

I was working over a 4U rackmount industrial PC that had an ATX PSU
in it. This had a supposedly "hard" power-off rocker switch and the
PSU even has an IEC socket on it for powering other equipment, such
as a monitor. So, I figured that the power switch was a real one,
that disconnected the PSU from the AC line.
Imagine my surprise when I put my hand on the PSU case that had been
powered off for two days and found it to be warm. It turns out that,
just like the 'soft-power" ATX supplies, it keeps a small DC voltage
on continuously. The secondary power outlet is switched by means of
a relay.
Fortunately, the thing usually is plugged into an IEC power strip
that's controlled from a master switch on the rack, so it normally
doesn't matter. I had the unit out on the bench and plugged in for
testing.
I really miss the BRS on PCs, when "off" really meant "off".
