I switched from Windows 7 to Linux Lite in January because I wanted better application support and improved performance. Now I'm interested in a desktop environment that offers more customization, similar to KDE Plasma, without making my nearly 12-year-old laptop feel sluggish.
My laptop is a Dell Inspiron 3542 with a 4th-generation Intel Core i3, 4 GB of DDR3L memory, and a 500 GB hard drive. I'm still learning Linux, so I'd appreciate beginner-friendly recommendations. Should I try a different distribution, or would changing the desktop environment be enough?

I would avoid KDE Plasma on this laptop, especially with only 4 GB of RAM and a mechanical hard drive. Plasma is much lighter than it used to be, but Xfce will leave you more room for applications. Arch-based options can be highly customizable, but they add complexity that probably isn’t necessary while you’re still learning.
The desktop environment matters more than the distribution here. Linux Lite already uses Xfce, which is lightweight and surprisingly customizable. You can also try Xubuntu or Linux Mint Xfce, but switching between them probably won’t give you a major performance improvement. Spend some time customizing the panel, menus, themes, icons, wallpapers, and window behavior in your current setup first.
Xfce is probably the best balance for this hardware. It can be made to look very different from its default layout, and it should run comfortably with 4 GB of RAM. Linux Mint Xfce and Xubuntu are both beginner-friendly alternatives, but Linux Lite is already a reasonable choice. An SSD would make a much bigger difference to everyday responsiveness than changing distributions.
I’ll look into replacing the hard drive with an SSD. I’d also like to learn what kinds of Xfce customizations people use beyond changing the theme.
LXQt is another lightweight option, and Lubuntu is a straightforward way to try it. It uses fewer resources, although some advanced customization can be less convenient and may require editing configuration files. For a first Linux system, I’d choose Xfce unless your current memory usage is a problem.

That makes sense. I was assuming I needed a completely different distribution to get more customization, but I’ll explore the Xfce settings and plugins first.
