General Question – PC Kits

I know the essentials of PC troubleshooting, networking ect. I was considering purchasing one of those PC kits to build a PC. Looks like you get a great deal with that and I am looking foreword to the learning process that goes along with it.

Iwas wondering, with the kit do you get everything you need to assemble the system. Do they come with instructions? What resources should I look at to start this project? By resources I mean web sites or books that may assist in how to configure the hardware.
