Custom or Big Retail PC?

I get asked this question all the time. Should I go out and build a custom PC or buy a off-the-shelf PC? My answer is, totally up to you. I mean, you can buy a pretty decent Dell PC for around the same cost of a custom built. Do you like to tinker around, build your computer from scratch? Or are you the type that just wants to open the box, plug it in and go? Me? Well, depending on the mood I'm in, I may go either way. After building my first machine though, I'm more apt to go the Dell or off the shelf route? Why? Just cause I'm lazy, work on computers all day and would rather have someone build it, test it, and support it. Custom built is fun and all, but it can also lead to some headaches either during the initial build (returning defective parts, etc.) you would probably find yourself banging your head against the wall. I certainly did, cause I found out I had some bad RAM sticks, then a bad motherboard (two of the four RAM slots were bad). Then come to find out my RAM sticks weren't quite supported on my board. Not speed wise but voltage wise. I just wanted to play my games for petes sake.
