I just received my system from AMZ. Interesting that there's no mfg's name or logo anywhere, but generally it was packaged well and all but the base seems to be machined more than satisfactorily.
So, before going thru the cleaning and checks of the screws as was outlined here, I did use "Break Free CLP" on the little bearings on the part that the tower screws onto, to do an intial cleaning, and I'm not certain how free it should slide; it does feel a bit gritty. But most concerning is, one side seems to be missing a couple of bearings :-(
When I side that part left and right, a space appears here and there and looks to me like a bearing or two is missing. This isn't the case on the other side. No spaces appear.
I was also wondering if the scratches that appear on the base is something others have noticed. They appear to be left by the mfs's machining process, but thought I ask.
Think I'll wait for any feedback before I proceed with assembly.
