I don't understand why multiplayer games don't run more on the server. If the server runs the game, then sends to client only what it needs to display the game and play sounds, the client doesn't have more information than necessary and a whole class of cheats is eliminated. There is no need for a client to know where an enemy player is if the player won't be shown on screen (wall hacks).
I think World of Tanks runs this way, and I've never encountered much cheating on there.
Some do, but its much more expensive for game companies and adds latency to some elements. Its generally a much harder problem for first-person shooter games - an enemy might be hiding behind a wall but the game needs to know the position of that enemy anyway because the player might move around the corner and see that enemy before the server updates or their game client might need to play noise that enemy is making faintly even if they are far away.
Players of these games are sometimes running their games at high framerates like 240fps which is much higher than the tick rates of these games too.
Plus it doesn't solve all the possible cheats that are out there, as there are some like aim-hacks that don't need any server information to work.
The difference for me is how much time do I need to spend to tweak the system, and how much frustration will I still experience after tweaking everything I could.
I found a Linux distro which suits my needs and desires out of the box, that I can just install and immediately get started doing whatever I need to do. It makes using a computer much more enjoyable.
"I really appreciate them including the keyboard here, as the display looks great but is definitely not all that responsive, so typing would be a lot more frustrating without this."
I don't know how much the fast refresh rate mode helps in that regard.
Built a gaming desktop for a friend almost 2 years ago; used GPU and CPU (maybe a few others things too), everything's going great. It helps that our local Cragslist offers efficient buyer protection.
Server-side, I also bought used Xeons for an old box and recertified 10TB Exos. No issues there neither.
The HDDs are a bit of a gamble, but for anything else I can only encourage you to buy used!
When you buy something on Le Bon Coin, if it's not conform to the description or outright broken, you can very easily get a refund from the platform itself up to 3 days after reception, even if the seller disappeared. I think it encourages people to buy used stuff by removing the main drawback which is "it may not work properly anymore".
