Building Vs. Buying

Advantages of Building:
-The selection of parts. When building, you have access to whatever parts you so desire. Pre-built computers don't provide that luxury, considering their parts have already been selected.
-Pre-built computers of the same model may have different parts. One seller may change to a cheaper processor and sell the same model with that particular processor. Building guarantees the parts you desire.
-By building your own computer, learning which parts interact with what components and such, you may acquire the knowledge required to troubleshoot and fix your own computer, avoiding tech support and repair bills.

Disadvantages of Building:
-The cost to build a computer as opposed to buying one costs a little more.
-If a part has something wrong with it, you must contact that specific manufacturer in order to fix it, whereas a pre-built only requires the attention to one manufacturer and warranty service group.
-Time consumption along with effort to correctly construct your computer is required.

Would I Build or Buy?
Well, seeing how I'm lazy and know little to nothing about constructing technology, I would probably just buy a pre-built computer - unless someone built it for me. I'm also fairly poor, so I wouldn't be able to afford a custom-built computer. But, I personally support building, considering the consumer gets exactly what they want, so long as they can afford it. I think getting what you desire is the most important part of being a consumer, don't you?
