Buriram, who are currently top of the league and are also defending FA Cup champions, booked their place in the last eight following a 2-0 win over Samut Songkhram and will now face Singhtarua.
Although the Port Lions are currently playing in the second-tier Division 1 League, they are currently on track to win promotion and have already claimed a top-flight scalp after beating Bangkok United in the Round of 16.
The tie will also generate plenty of added interest given it will pit Philippines' two representatives in Thailand - Thunder Castle hitman Javier Patino and Singhtarua's new winger Patrick Reichelt - against one another, provided both are fit.
Muangthong, who eased into the quarters after a 5-0 win over Phuket, have also been pitted against a Division 1 League outfit that are currently gunning for promotion in the form of PTT Rayong.
The Oil Millionaires are currently second in their division and boast a number of big names in their squad, including Thailand striker Kirati Keawsombat, Ivorian defender Amadou Outtara and Japanese midfielder Terukazu Tanaka, who briefly played for MLS side Real Salt Lake.
Elsewhere, Bangkok FC will take on Bangkok Glass, while the final last-eight tie is an all-Premier League encounter between Police United and Chiangrai United.
