You can save yourself a heap of cash if you build this yourself. I put this together at Newegg in just a few minutes. The only thing you'd need to add is the case you want and they have tons of cases to choose from. I even picked out a Blue Ray DVD Recorder and it's STILL way under the price you found. This one only has 16GB of RAM (as opposed to the one you picked that has 24GB of RAM). You can choose a different motherboard if you absolutely have to have 24 GB but I think 16GB would be fine. Oh, I forgot a video card with that as well. I'm almost certain the Dell you're looking at has on board video. Unless you plan to buy a video card, you'll have to add that to my list as well.
If you are going to build yourself, consider this board instead.

I bought one of these recently for a new system and the 20GB SLC SSD turned an otherwise weak hard drive into something that feels every bit as snappy as my main system that runs exclusively off an SSD.
Also, don't forget a case & power supply.
