I completely agree with you about Micro Center frequently changing. I remember when visiting their SoCal store, the books section was moved to what appeared to be a clearance area and found a large drone display in its place. The Fry's in my area seemed like it had 2-3x the square footage, but maybe the same amount of inventory (or less) than Micro Center did.
The Micro Center also used to have this awesome display of old logos (such as the rainbow Apple logo, Compaq, Packard-Bell, old Microsoft logo, etc) from various hardware and software companies that wrapped around the front and sides of the building in all its 90s glory. Sadly, I found it missing as of earlier this year. I wish I took a picture of it while it was still up. Did the Cambridge store have a similar "logo ribbon"?
