Cutting Helders RetroPSU to make it a little smaller?

I designed a custom case that used Helders RetroPSU (v1) and now I'm wanting to build a second, but the old one isn't available anymore and the new one is significantly bigger and won't fit.

I'm hoping to be able to trim the bottom of the board a little, cutting off straight removing the NC and Output2 -> EN pins. This would also remove R7, R8, R10, C10 and the GN and OR LEDs.

Would this be possible to do without destroying the board? Sure I'd lose EN on output2, and the charging / charged LEDs, but I don't know what R7/8/10 or C10 are doing for the board.

As an aside, I'm a little bummed to see the loss of the remote LED pads that the v1 had, but I digress.

Only @Helder can answer for sure. Did you message him? I'd guess that two of those resistors go with the LEDs, but I'm not sure what the other resistor and capacitor are for.
