I asked a private vendor selling Dell systems a quote for T-5810 with one 500 GB, Two 3 TB and a DVD-RW dive and he did give me a quote so I have asked him how he is going to fit all 4 of them. I will post what he says when I hear from him.
His answer might help all of us.
I do appreciate all your help very much.
hmmm... not sure as to the question, but it isn't hard to see how he is doing it as that system supports 3x HDD easily as long as there is a slim DVD drive... even better still.. you can add +6x 2.5" drives for more disk space as long as you throw in a controller as well...
