Round holes are an option for the buttons - the final PCB has 
mounting pads for three different types of switch: the original 
sqaure ones I used (with the clear caps to take labels); standard 
12mm tact switches as used in the TB303/TR606 etc (which you can 
certainly get square tops for, and posibly round ones); unimec tact 
switches with 9mm round caps.

You'd still need to cut a rectangular hole for the LCD...
Unless, as I have considered, you use a perspex front panel.
Then you wouldn't need to drill holes for the LCD or LEDs.
And it would look very techno ;-)

A custom made case is still the path of least resistance, tho'.
