Not exactly both at once, but I was able to fit 2 different VR sets. 1- Samsung WMR Odysseys+ with 2 controllers. 1- HTC Vive with deluxe strap, 2 controllers, 2 tracker beacons, 3 power cables, junction box, 2 micro USB charging cables, 2 USB sockets. The only thing I found is that the sides protrude a bit because of the headset with the headphones on. Otherwise everything fits. The suitcase is heavy but nothing compared to those bulky travel suitcases. Remember you sacrifice size for protection. I wouldn't recommend carrying $400 gear in a $30 case (price at the time) for too long.
