You'll be fine sticking with the Intel HD3000 graphics. The mini also supports a full sized HDMI port so you won't have to buy any annoying adapters. One thing you should note though: The mini does not have a CD drive, you can get around this if you purchase an external drive, but if you are planning to rip any blu-ray or dvd video it is an extra expense to consider.
The other thing to consider is the mini only has 2GB of ram, I recommend 4GB for decent performance. It's an easy enough upgrade to do on the Mini though, so you shouldn't have too much trouble.
