Hello Alfonso. I am sure you are already going in a better direction with help from the guys and gals here. I am a little late to the party but I am an AVID Diablo fan and I am chomping at the bit for Diablo 3.
I have seen that EXACT computer setup at Costco (not sure where your source is though) and it should run Diablo though im not sure about Skyrim BUTTTT my thinking is you will have to play it on low graphics settings. That computer is basically a Windows Professional setup (IE Word, Excel, Microsoft Professional software) and not really for gaming.
Gaming stresses your Graphics Card and Central Processing Unit or CPU (basically, the brains of the computer) and that computer that you first posted will not handle that well or for very long IMO.
I am not sure if your upgrading a rig or building your first one but I would suggest something better. AMD with about 3.0 GHz and a graphics card from 2007-2008 or Intel with about 2.8 and a graphics card from 2007-08 should run Diablo BUT again you will NOT get the best, you will get low to medium settings. Anything 2009+ will handle Diablo on medium to MAYBE high (if you get really new components)
For reference Diablo runs about the same as Starcraft2 (which I own) graphics wise and stress wise. Their engines were both started about the same time Diablo 3 is just taking forever.
Feel free to ask me anything or for you or any of these guys to correct me if I am wrong. I will see the message in my inbox and reply.
Also, for everyone commenting here is a list of graphics cards that will run Diablo 3:

The ones higher to the top can run the game on LOW settings, the middle of the list can run on MEDIUM and the bottom of the list can run it on HIGH/ULTRA.
Again, similar to SC2 if your a Blizzzrd fanboy like me.
Hope that helps
Late Edit: Skyrims engine is a custom engine they made just for that game. That game is more stressful on your computer (especially for long time periods) than Diablo ever would be. I would suggest a graphics card from 2009 at least (or later) and an Intel CPU with 3.0 GHz or an AMD with 3.3.
Sorry for the general explinations of things, not sure how familair you are with computers or games, just trying to make it easier to read and for others to contribute.
