Working with the X58 Extreme6 was pretty simple. The layout is clean enough that we had no issues getting everything setup and installed. The only problem that I personally had with the system was the sheer amount of shovelware that comes with the full installer. For some reason it pushed a ton of items onto the desktop. Even at 1920x1080 resolution we had a full column of icons right from a fresh install! Some of these do not need to be desktop icons at all.
We also were not happy to find that much of the "value" bundle only comprised demos or trial versions of software. I hate to say it, but the installation of something that has limited use is not a value; it is much more of an annoyance. True, there are a lot of items there, but I would rather have one full version of a really good piece of software than five trial versions.
Most consumers are going to feel the same way, so I think ASRock could do better here. After we got past the issues with the shovelware and bundled software, we quickly had things moving.
