a bit on building the actual computer is always good, I have build a few.... tha hard part is totaly the processor, it needs to match the motherboard, the assembily is real simple though, your mother board manual is very important for first timers, this shows you in there somewhere how to attach the power switch ecxt wich is a bit different in each motherboard. your powersuply will plug in using the long bar to your motherboad and the smaller ones to cd and hard drive. it is realy simple kind of like plug and play because other than the power button to the motherboard most stuff just plugs in where it fits and more online forums like this are a great place to learn this stuff, thats how I learned most of what i know, by doing and when i was stuck i would google my problem, also if you realy want to build your own computer and you buy all your stuff in a smaller store and you buy ALL of it there they MAY build it for you for free.
