Lidl does have some zero caffeine and zero sugar cola. They introduced it this year I think.

Can’t get it to work either, maybe some of the games are blocked in some regions?

I don’t know codecademy, but there is also:
cs50x
Don’t know what people think of it, but it helped me a lot in understanding the basics of programming and I really liked the exercises. But I am just a hobby programmer working on smaller stuff.

Yeah, Maybe one of the rails on the PSU broke? Can something like this happen? Some parts of the motherboard seem to get some power but, I do not get any of the main status leds.
I will try to look at the cpu later, I try to get a second psu for testing…
