You shouldn't need to use DisplayPort for that resolution (but might
want to due to the blanking problem on the HDMI port). Based on other
reports, the HDMI output should be able to do 1920x1200, so 1600x1200
will be fine.
HDMI is basically single-link DVI, and its maximum resolution is a
question of total number of pixels per frame, not the specific number of
lines or columns. Single-link DVI can do just over 2 megapixels (e.g.
1920x1200), but can't achieve 4 megapixels (e.g. 2560x1600). The latter
is possible through dual-link DVI, which has twice as many pins carrying
the video signal.
I'm able to do 1920x1200 through single-link DVI, but haven't tried that
resolution via HDMI as I don't have any displays with an HDMI input that
support resolutions higher than 1920x1080.

That's another reason I'm thinking of getting this Mini rather than
waiting for the next model: it might get a redesign next time and drop
Firewire in favour of a second Thunderbolt port. That would add to my
cost as I'd need a Firewire adapter to keep using my existing drives.

I'd hesitate to put the Time Machine backup on an internal drive in a
Mini, as it complicates the situation where there is a fault with the
Mini which prevents access to either drive, and you want to restore the
backup to a different computer.
With Mountain Lion, you can of course have two Time Machine backups, one
on an internal drive and the other on an external drive. ML will
alternate between them for each backup, if both are available.
My current Mini (late 2009) is the Server model, which I got
specifically because I wanted Mac OS X Server and it was a cheap way of
getting Server 10.6, which would have cost half the price of the Mini
just to buy the server OS for my older Mini. That is no longer a factor
with the much cheaper pricing of Server in 10.7 and further reduction in
10.8. The optical drive wasn't a consideration - I almost never used it
in my older Mini.
I was intending to use one of the internal drives to run the server, the
second one for data storage, and an external Time Machine backup drive.
Shortly after I set up the server, I discovered that the internal drive
I was using for the OS had developed bad sectors, which rendered the
system unusable. I had to erase the server and set it up from scratch,
as I hadn't been expecting a problem that quickly and hadn't done a
backup of the server yet.
I did the second install on an external Firewire drive (which was faster
than the internal drive anyway, for that generation of Mini), and I've
run the Mini with the external system ever since.
The internal drive with the bad sectors has subsequently been used to
store EyeTV recordings and it appears to be OK - it has been close to
full and I haven't seen signs of I/O errors on read. I expect the bad
sectors were replaced by spare ones on write and if it is getting worse
I haven't noticed yet.
I'm intending to have a close look at the drive's detailed SMART status
before the AppleCare expires, so I can get it replaced for free if
necessary. I'll need another Mac Mini if I need to send this one away,
hence my interest in buying the 2012 model soon. My 2009 Mini can run
Mountain Lion, so it could be an emergency spare for my 2012 Mini if the
latter develops a problem.
