I promise you do not need to hire someone, this is very simple stuff. Most parts and cables snap right into place and it's very obvious where they go. From my experience, the hardest part to finish installing is the heatsink/fan but even then, it's more a matter of the thermal paste application. YouTube a PC build with your processor type as I believe AMD and Intel use different heat sink brackets.

Basic notes, good practice: Use SATA 0 for your main hard drive Get good thermal paste or you'll be replacing it sooner than later Use ESD gear to protect sensitive components RAM arrangement for motherboards varys. If you only have two slots, just shove in the matched pair. If you have 4, check your motherboard specs and verify how to install a matched pair. Nothing should be super tight but you will likely have to apply more pressure than you think on certain components. Certain boards have a tight fit for things like graphics cards.

Take it slow, I promise you can figure this out buddy
