Okay, that's fair. It was when the version came out a long time ago, so I'd forgotten. What I'd asked you, though, was what edition you were using. Now you tell me it's MATE.
MATE is a desktop environment (a DE) that's no longer supported, even by Solus. Solus is about to release version 4.5, in which there will be the usual Budgie, GNOME, and Plasma DEs, but also the newest addition to the Solus family, Xfce, which will be taking the place of MATE. But that's not really important right now, as any of the Solus editions (except maybe GNOME) would be a good choice, and that includes Xfce.
The development team is even working on a utility to help current MATE users transition to Xfce. They won't even need to installl Solus again. It'll be like computer magic.
But if anyone can help you get Solus installed on your home-built computer, it'll be people like Bret, and Axios, and me here in the forum. We've been using Solus for years, and don't have any problems installing it on computers for the first time.
There's nothing wrong with home-built computers, if they have the right components in them. I've built several over the years, starting with a case, and a motherboard, and disk drives. But there's one thing that might keep you from installing Solus on your home-built computer: Solus is designed to run on 64-bit computers only. It won't run on 32-bit machines, which haven't been sold for decades. If that's the kind of processor in your home-built computer, you won't be able to run Solus no matter how many times you try to install it.
Fortunately for you, there are some other distributions that do still offer a 32-bit version, and there's been discussion here recently about them. You could use the forum search feature to find and read those messages. That's if your computer is a 32-bit machine, but we don't know that for sure. Like I said, they haven't been made in decades, but we just don't know what you're working with. That's just one possibility for why you're having trouble installing Solus, but not the only possibility.
Do you know what kind of central processing unit (CPU) is in your home-built computer? Is it Intel? AMD? Something else? And there's always a model name or number, like Pentium or Core 2 Duo. If you could provide us with the make and model of your CPU, we could look it up and find out if it's a 64-bit model, and capable of running Solus. Does your computer have any USB ports? Do you know what those are?
There are lots of us here who can help you to get Solus installed on your computer, if it's able to run a modern operating system. But nobody here is going to be able to help you without knowing the capabilities of your home-built computer, especially what kind of CPU it has. Please see if you can tell us some more about what you're using, and we'll try to help you.
