Converting RAMPS 1.4.2 for 24V (no replies)

I picked up a RAMPS 1.4.2 from GermanRepRap recently and was rather bummed to see that it uses 16V capacitors. I'm looking for the appropriate capacitors to be able to run 24V. I see quite a few on Digikey, but would feel reassured if I could find what others are running.
reprap.me shows a ramps board with 35V capacitors, but I'm having trouble finding a BOM to know the part number for those specifically.
Anyone have any help?
