Does this model have expansion slots for a better video card? I want to go out via HDMI to a large flat screen monitor.

Weather it does or doesn't, does not matter. That Pentium D is obsolete. It really belongs in a scrapheap...

Running modern software on that thing will be atrocious at best.
 
You can put a low profile PCI Express card in one of those, but the power supply is something really weak (like 280W) so you can't put anything powerful in it.

Bingo.
1. It is a 280-watt PSU, which is a proprietary design. So you can't upgrade that.
2. You aren't going to find a video card that is much faster than what you have with the correct design (LPF) and power limitations.
3. And even if you could take care of that, the Pentium D would be holding back the power supply. And even if you did upgrade to a Core 2 Duo (they are pretty cheap), you are going to make the power limitation from #1 even worse.

Here is another thread on the subject:

Suggestion: Save your money and build/buy something new(er).

False. Pentium D were absolute power hoggers. A Core 2 Duo should drop peak power consumption 50W or more (Those were the times that Intel used the TDP as a sort of "average" metric. High end Pentium D Smithfields could happily eat around 150W all by themselves).
