One thing y'all have to remember is, SUPPORT
Dell has free support that goes with everything that comes along with it. If you do not feel comfortable you can fix any problems that come along, or dont' want to figure out what company to call I'd suggest a prebuilt...
Don't get me wrong, I myself am all over building my own and I learned a hell of a lot when I did build my own. This site will always be here for help of course
So take my advice how you will... if you have some spare timeand this is something you are really interested in, by all means DIY (do it yourself).
Otherwise, go ahead with a prebuilt BUT STAY AWAY FROM COMPAQ (pc's)
LOL
