Just annoying little issues like the six months it wouldn’t power up first time. Turned out to be a GPU initialisation problem. But when you only have one type of each component and the only way of debugging is swapping parts until you find the problematic one, you have to live with it. For some people it never works and then you have to deal with several vendors you bought the parts from all of whom point at each other. And if you buy off the shelf then you really have no idea what crap you’re being sold unless you want to pay a very high premium.

Every PC build takes a lot of risk on. Not one I’m willing to take any more. Commercial desktops are either junk or too expensive. I’d rather use a single sourced well integrated appliance.

Edit: also the dubious nature of some parts is a worry as demonstrated here https://www.reddit.com/r/WatchPeopleDieInside/comments/g0420...
