This is my third Dell and I take care of what I put in it....   I keep it clean and treat it with care...  I have to physically clean the insides soon.. fans, connectors... I don't have much problems except from the software I install in it...  I don't like the proprietary hardware business but...... 

Customer support from people that can not speak "the English" always rubbed me wrong..

BTW...  building your own can leave you without a boat in turbulent sea of problems....  Because you are left without a specific place to call for help...  If you have a problem and it is not determined whose at fault.. HARDWARE OR SOFTWARE...  you can get ping ponged from manufacturer to manufacturer....   Making your own means you are fairly sure in your general and beyond knowledge of computers..

not for the faint of heart...
