I honestly really recommend reading up and building it yourself, you learn more about the components, and it can later help you figure out what you want/need to upgrade, fix or replace.
sites such as logical increments, pcpartpicker, reddit.com/r/buildapc, this site, and a ton of others can help narrow parts down, youtube is GREAT with tutorials, linustechtips on there can help with a lot of tutorials to name one off the top of my head...
Save the money and put it back to the machine's budget or back in your wallet.
That's true, I'd be more skilled for future upgrades and stuff... It isn't actually laziness, it's the risk... I actually would love to do it myself, but what if I screw any component? I guess that isn't very probable, but possible.
I'd also save money, true... But it's just €30...
Thanks for your answer! I might go and build it myself.
