Any reason you don't like Shuttles? I just put together an
Aopen EZ482, since I couldn't get a Shuttle in my area.
It's average, I think. Works just fine, not too loud, and installation was simple. The design is good, overall, although I think the front panel plastic feels...cheap. But it's pretty modern and will last me a few years.
I do have one complaint - I can barely hear some noise/static on my headphones for some reason, when I do stuff in Windows like maximize/minimize applications. Haven't figured out why.
