There is a whole separate section of the forum setup for building new systems.

Systems > Homebuilt > New Build
If you want to hop over there you'll find a lot of others doing the same thing you are.

Have you set a budget for this project?

If you fill out the form in *How To Ask For New Build Advice* you'll answer all the standard questions that help things get started.

You need proper knowledge or a will to learn.

Here is a Step-by-Step Guide to Building a PC

Look over the forum's "System won't boot" checklist to see some of the common build errors and how to avoid them.

-> The usual advice; read the manual / install guide; look at the parts, read the manual again and if everything makes sense and looks right - then go ahead with the install.

While you're waiting for delivery you can download the online version of the motherboard manual and start getting familiar with it. Same for the other parts you want to order if they have install guides or manuals available.

You need money.
