½mm spare space FTMFW!
Shall I tell you what I did Marios mate? it was quite destructive, but I didn't want to risk desoldering with a pump or braid, so I took a pair of small needle nose pliers and applied fresh solder to each pin on the headers, then used the soldering iron on each pin to heat then gently pull out each pin from the topside and through the plastic of the IDC headers. It means that you can't put them back on (unless you find some new IDC bits), but you can be sure you won't risk damaging your Delfina board. And yeah, be VERY careful with the two small capacitors hand soldered underneath. Those two caps are the difference between your machine working and not working with the BPPC installed! They need to stay in place, but again, soldering iron on pin, gently and failry swiftly pull the pin, and the caps will stay in place
The big electrolytic capacitor should be easy enough, just pluck it out slowly, then add some bits of old resistor cut offs, then mount the cap at 90 degress on them.
The CDDA headers are quite easy too, they can be eased out slowly as long as you apply some fresh solder and run the iron over the 4 pins swiftly whilst gently pulling with pliers.
Adding the clock ribbon cable and CDDA extension cables is just a matter of time an patience.
And lastly, I recommend you find an old piece of thin floppy perspex/plastic to stick under the Delfina to avoid shorts, and add some insulation tape or something on top of the oscillators just to be safe.
If you need any more help mate, be sure to ask
