This wildly depends (for that store, at least)--if you need something very mainstream you'll find it but they don't have a lot of things that I'd consider pretty obvious for a tech store. Their computer cases, for example, are mostly X-TREME in nature and they have few-if-any HTPC cases at any given time, and definitely nothing that can rack.
On the other hand, what I do really like about them is that they sometimes, for high-demand items, don't actually update the online stock numbers. I was able to walk into the store to pick up some RAM and walk out with a 3900X because they were saving them for in-store customers.
Cases that aren't designed to appeal to 12 year old boys are hard to come by, period. Manufacturers have decided that everything needs to have sexy angry facades and RGB lights - this has a lot more to do with product people at the manufacturers and less to do with the actual market. Ditto motherboards, especially.
It would be nice to not have to wait for Amazon to get something for a project, is all.
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"?
Just going there takes me back to the proper “computer stores” that ceased to exist after the 90s. Actual PC parts and not full of appliances and movies/music
frankly a boring looking store

They're always changing though: they had a console video game section for a while, now thats hobby computers (rasbery pi and co). They had a camera section, but thats gone. Computer books, gone. So they seem to be paying attention and a few years back they finaly went to a one line checkout (still takes too long, but its better).
