i'm afraid there will be no vfd display and am not planning to use vfd.
just finished the machining of the chassis, the dimension is: 150 (w) x 240 (d) x 55 (h)
obviously, there is some extra space left inside and additional psu could be added but there is no room for an IEC socket on the back panel.
the machining of of the front panel is yet to be finished.
