I currently use a Lenovo Legion gaming laptop, but it has started developing serious display problems. The wallpaper first turned black, then the entire screen began switching between black and white, and the laptop also overheats despite having its fans cleaned less than a year ago. Since I'm doing a master's degree and can't be without a working computer, I'm considering either buying a prebuilt desktop or assembling one myself. I don't know much about PC components, compatibility, CPUs, motherboards, or choosing parts that can be upgraded later. I'm based in Portugal and have a budget of roughly €1,200–€1,500, excluding the monitor, keyboard, and mouse. I'd use the computer for gaming, university work, writing assignments, taking notes, streaming videos, and watching movies. A white build would be my preference, although I understand that matching white components may cost more.

There are ways to get fairly close to an all-white setup for around €1,450, though you may need to compromise by using some black components with the white case. A carefully selected parts list can still look very cohesive without paying extra for every individual white component. The proposed build is a good starting point, but check current Portuguese pricing and availability before ordering.
A compatibility-checking parts site is a good place to start because it flags many common issues between components. Try putting together a draft build, then have someone review it before buying anything. For this budget, an AMD AM5-based system is worth considering because it gives you a more modern upgrade path, although memory prices can be surprisingly high right now.
The prices are definitely my biggest concern, but my laptop is now struggling even with games like Genshin. I’m also confused about the differences between CPUs and whether the motherboard matters for future upgrades, so I’m starting from almost zero. Thanks for the recommendation!

It actually looks really nice! I think I’d be happy if the case were white, even if the internal components weren’t all matching, since I’ve heard white parts can make the build more expensive.
