Pros: I wanted a system that would be well supported in the years to come, and HP does very well in that regards; such as, bios, drivers, and documentation downloads all from one website.

The use of this machine was for general office work, and web surfing, as well as wanting a machine that came with Windows 7 Pro. I have not used, nor will it be used as a gamming station. With all said, the computer has speeded-up both my web surfing and business applications from an AMD dual core XP box. It is well designed both internally and externally, but the screw-less case requires special little mounting washers to install additional Hard Drive/DVD drives, but if you are thinker, you can just use some rubber O-rings under the HD mounting screws.

It comes with Win7 pre installed, but no Win7 disk, so back-up the OS ASAP.

Cons: Now, the power supply is not a standard unit, and if it stops working, then an HP replacement will be required, but the good news is that the HP power supply can be had for about $29.00 USD! Sure, you could modify a different power supply, but you better know what you are doing.

Also, securing Win7 is a chore and a half.

Other Thoughts: I ordered the HP DC7900, but an Elite8000 was shipped to me; or I should say a Hybrid Elite8000 was shipped, as it appears the case looks like a DC7900, but internals are that of a HP Elite8000.

Also, it appears that this computer might of been a bench testing unit for external USB devices. Why? because a couple of the USB ports are a bit sloppy, and that takes a lot of plugging/un-plugging for that to happen.

Pros: Shipping was way fast, and everybody loves that! Does what it is to do, and ups the Win7 speed rating. Installing was way easy, and no more worries about bumping your computer when it is on.

Cons: No Cons.

Other Thoughts: Samsung has a five year warranty on these, and that is a good thing to look for when buying these things.
