The good with Dell is you get the system built for you and if you buy the extended service plans you get support
the bad with dell is they will use nothing but OEM parts, the BIOS will be limited and performance features locked out and you will end up with a Windows install disk that has a process list like this one running by default:

There you have it
Dell is for businesses and people who need technical support and who do not require true high performance
Some people buy dell and clean up the Windows install, or even buy their own Windows disk and throw dells in the garbage. That helps but you will still only be getting an OEM motherboard and BIOS which will most likely lock you out of any manual fine perfomance tuning and will probably come with an OEM video card which is also not the full deal. Dell does not buy top shelf parts theu buy 'lots' of OEM grade components that allow them to lock their features so the user can not override what dell considers the performance limits, which is usually pretty low on the scale too.
Add to that, hardware upgrades such as processor and memory sometimes need BIOS updates and if dell does not write the BIOS themselves, you cant go to the motherboard company and download an updated BIOS. you are stuck, which is how dell wants it so you have to upgrade the hardware.
Then there is the PSU. Some of those dell towers will no take a PSU upgrade other than their own hardware. It depends on the area in the tower the PSU fits. Sometimes you can, sometimes you cant. PC Power and Cooling had to make special power supplies just to help out Dell customers because they were being shafted by dell on upgrades.
Anyway... there is the good and the BAaaaaaaaaaaaaaaaaaaaaaaaD
