This one is out of date. HP no longer has it on their site. It uses an AMD quad core CPU (way slower than Intel), has limited memory, only a single disk (three 7200 RPM disks are advised), the wrong graphics card (no hardware MPE support) and further details can not be found.
It is resonably OK if you ONLY edit very simple SD DV projects and have all the time in the world. It is at least 20-30 times slower than a fast system. It is not suitable for editing HD.
I agree with Harm, with regards to that PC. It appears to be an HP model manufactured specifically for Sam's Club and appears to be unavailable anywhere else.
As for the components, there are a lot of drawbacks to that PC:
1) The AMD CPU is almost as slow as a three-generation-old Intel CPU. (Meaning that it is almost as slow as a five-year-old Core 2 Quad, and significantly slower than a four-year-old i7-920.)
2) It completely lacks a discrete GPU. It relies on an APU embedded into the CPU for graphics.
3) 8GB of RAM is not enough RAM to run Premiere Pro CS6 to many people's liking. 16GB (or better, 32GB) of RAM is recommended.
4) It has only a single disk, which makes performance in Premiere almost twice as slow as it otherwise normally is.
5) Its case is extremely cramped on the inside. Airflow is poor inside the case, which severely limits any GPU upgrades to that PC. In fact, it might not be able to accommodate a GPU that's a large enough upgrade from onboard without having the GPU overheat.
6) Finally, its included PSU is too weak and too low of a quality to accommodate any GPU upgrade, in any case.
