However, they've got their eyes on more than the Eastern Conference crown.
"Cleveland," owner Dan Gibert said, addressing the crowd. "We're not settling for this."
It will be the fifth straight visit to the league's showcase event for the inimitable James, who returned to Cleveland after four years in Miami to try and end this city's championship drought dating to 1964.
J.R. Smith added 18 points and Tristan Thompson had 16 points and 11 rebounds for the Cavs.
Unlike 2007, when James celebrated at the final horn, he was very business-like after the clock hit zero. Standing at center court, he turned to Smith and said "four more."
Jeff Teague scored 17 and Paul Millsap added 16 points, 10 rebounds and five assists for Atlanta, which won a team-record 60 games during the regular season and made the conference finals for the first time since 1970. But the Hawks were no match for the Cavaliers and had no answer for James, who nearly averaged a triple-double in the four games.
It was a tough way for the Hawks to end a remarkable season. They survived a tumultuous offseason, and their young roster gelled in January when they became the first franchise to go 17-0 in a calendar month. They went on to win 19 straight, improved their win-loss record by 22 wins over last season and beat Brooklyn and Washington in the playoffs to make their first conference finals since 1994.
But an injury to starting forward Thabo Sefolosha in April was followed by DeMarre Carroll injuring his knee in the series opener, before Kyle Korver's season ended in Game Two with an ankle injury.
Those all hurt, but it was James who inflicted the most pain.
James carried the Cavs to their first finals appearance eight years ago, when they were swept by San Antonio. Cleveland was a heavy underdog then and it was assumed the Cavs would get back again. But James left in 2010 to join the Heat, a move that dropped the Cavaliers from relevance and into the lower rungs of the standings.
His return to his home team, to play alongside Kevin Love -- out for the season with a shoulder injury -- and Irving immediately made the Cavaliers the team to beat in the East.
It didn't go exactly as planned under first-year coach David Blatt, who left his family in Israel to take the Cavs' job.
"We're in Cleveland," Blatt cracked. "Nothing is easy here."
The Cavs lost center Anderson Varejao to a season-ending Achilles injury in December and they were 19-20 before trading for Smith, Iman Shumpert and Timofey Mozgov, a trio that provided the intended boost.
Irving, who missed Cleveland's previous two games with tendinitis in his left knee, scored 16 and the All-Star point guard looked better than he has in weeks.
Unlike Game 3, when he missed his first 10 shots, James started much better and scored 15 in the first half as the Cavs opened a 17-point halftime lead. They pushed it to 20 early in the third, withstood a brief rally by the Hawks and spent the fourth quarter playing their reserves and getting ready for a party and some time off before the finals.
The Warriors are their likely finals opponents, leading Houston 3-1 in their series with Game Five taking place tomorrow afternoon in Oakland.
