I just tried googling it but couldn't find anything reliable. One website listed about 10 teams with significant cap space, another one just two or three. And none of them used the new actual cap number, nor were up-to-date with the latest trades.
Here's an article that at least gives details on how it came up with its numbers:

Here's a summary:
Atlanta - no cap space
Boston - 15.4 projected cap space
Brooklyn - 22.6 projected space
Charlotte - no space
Chicago - 14.8 projected space
Cleveland - no space
Dallas - 22.0 projected space
Denver - 11.7 projected space
Detroit - no space
Golden State - no space
Houston - 5.7 projected space
Indiana - 13.6 projected space
LA Clippers - no space
LA Lakers - 17.5 projected space
Memphis - no space
Miami - 30.9 projected space
Milwaukee - no space
Minnesota - 10.6 projected space
New Orleans - no space
NY Knicks - 13.9 projected space
Oklahoma City - no space
Orlando - 15.8 projected space
Philly - 46.7 projected space
Phoenix - 11.3 projected space
Portland - no space
Sacramento - 14.8 projected space
San Antonio - no space
Toronto - no space
Utah - no space
Washington - no space
At the very least those numbers should all be reduced by 2 mill each, due to the cap being lowered to 99 from the projected 101.
That would predict 11 teams with more than $10 million in cap space and only 5 teams with more than $15 million (if I counted correctly).
