Was the part list okay? No part list? I'm thinking about buying a prebuilt PC, but I have some concerns. At the core, if the cooling and power supply are good, is that usually enough to avoid issues, right? Also, it's important to find a place where I can get support during the warranty period. What's your general approach to this? What points do you always check?
What should I look out for when buying a pre-built PC?

Last year, I bought a prebuilt PC from a friend due to these exact concerns. Here’s what I learned: cooling and power supply units have way more nuances than you’d think. I was like you—"if it’s good, it’s good"—but a month later, my CPU temps were running 10°C above normal. Why? The builder hadn’t seated the fans properly over the CPU or used enough thermal paste. I fixed it by reapplying paste and reseating the fans, but it was a waste of time.
As for the PSU: they gave me a 650W 80+ Gold unit, but I only needed 550W. They didn’t spend extra—just called it "standard." The system runs fine, but I’m wasting power on unnecessary wattage. Warranty-wise: the company offered a 1-year guarantee, but if the build quality is shoddy, you’re stuck dealing with a new service provider. My advice? Research the builder’s reputation beforehand, test the system thoroughly after assembly, and try to get the warranty through the manufacturer (some big retailers also offer assembly services).
Mounted PCs are a comfortable option if you don’t want to deal with selecting parts, but there are key points you should never skip. Coolers and power supplies are essential, that’s for sure, but also check the motherboard: make sure it’s compatible with your processor and has enough RAM (at least 16GB these days). In my last DIY build, I messed up with the motherboard and had to return it, so better double or triple-check before buying.
Another critical issue is the warranty: some stores assemble PCs with generic parts and then leave you hanging if problems arise. Look for shops that offer real post-sale support, not just a 1-month return policy. I now work with a local site that gives 2 years of warranty on builds, and it’s saved my skin more than once. If you can, ask them to run a stability test before you take it home—it removes a lot of worries.
