You can likely ask pre-sales tech support every question you want to,
it will likely resolve nothing. The odds of any answer they give you
(on something like this) being right is 50/50 (ie not to be trusted
nor relied on). Checking the manual and what other people trying to
do similar things say is going to be much more accurate (google the
model). Most tech support are trained to be confident in what they
say hence you can never tell if they are a deer in the headlights
making things up. I have only really caught them at the time when I
immediately know what they just said was not true. So if you ask all
of the questions you may only end up buying from the company with the
most confident sounding tech support person that made it all up.
It is not a great state but it seems to be reality. I won't waste the
time asking the questions because the accuracy of the info I get is so
low that the info cannot be used.

you were planning to keep the installed Windows system (which I wanted to do), then there
is a procedure you can Google for (it might have even been referred to on this list) that
will allow the Dell-installed Windows to boot in non-RAID mode. I followed the directions
and can now dual boot Windows and Linux out of the GRUB menu.
