With Dell, if anything buggers up, it has to go back to Dell to fix (kinda like crApple Crapintosh)
I came across a few Dell laptops and the battery needed fixing so I asked a friend at a computer store he worked at and he told me to see Dell...
Similar to their printers, I get ppl calling up and coming into my shop asking for a replacement ink cartridges and I say, the best I can do is refill it otherwise you have to order online through the Dell website.
Dell might make it a great package deal and sell you the PC, but I'm not buying it.
Your best to get a PC built to your specifications.
So "word processing", "internet browsing" and "Gaming" is what you want it for then the ppl who build your PC will be able to say what's suitable for that set up.
Not much point to spec down as a lot of the entry level / technology these days are at a very high standard.
