If I recall, isn’t Swiftech a company that build custom parts for LCS? I don’t think I’ve seen them have a ready-made LCS product.
But like Excellence said, building your own pc these days is like plug-&-play, it’s so simple. The only thing you need to know is your cpu socket, ram socket, and the type of chipset it has. The other thing to consider is if your video card fit the chassis. The rest is all about budgeting.
Honestly, you can go to any forum and make a post of your budget and the purpose of the pc, and people will volunteer their time and help you pick your parts.
