Thanks for all of the feedback!
I will do a clean install today... I like to know how everything works... That is usually a good first step... If I remember correctly... nothing too weird about installing OS 4.1... but then again, I have only ever tried on an emulator...... I guess I will see how this goes!
I know Amigasociety had shipping damage.... which is never fun.... and a bad network card (I think he is correct... these things are probably super cheap with poor quality control... hopefully we can use the onboard networking someday soon....) but I have had an overall great experience with Amiga On The Lake. I always hate shipping tower computers.... I would almost prefer to get the kit sent to me in parts, and I build it.... I think it is safer....
As for the splash screen, the initial boot screen does have a nice AmigaOne X5000 logo on it... but the OS screen (until you change it) does still have the pre-release designation.... that is why I was wondering if we needed to update... but it sounds like that is not only not needed, but it won't work anyway as our X5000 build is still a bit unique.
Thanks again!
