I can't imagine how many lovely Filcos you have violated... 
When I visited, there were at least 3 completed ones that had been modded and parts for at least another 5 that looked new.
I take apart almost everything, especially if it's a keyboard and I know I can repair it if it breaks. Who needs a warranty when you can save time and do a better job fixing it yourself?
anyway, you can likely recoup most of it by reselling as jacobolus says. variables usually sell for a little less, and used keyboards a little less as well, but all-in-all I think it's worth.
Then again, I'm probably biased because I support hacking on all your stuff, but in this case you have very little to lose.
