I went with a panel mount because it is a pretty common problem for BOTH Sega CD systems to blow fuses. And if it ever happens again, it takes me only a minute (literally) to change and this way, nothing is just laying around inside the system.. Compared the model 1 I'd say a good 30 minutes to change and 10 minutes to change in a model 2.
Plus the panel mount I used, I think it actually looks like it's supposed to be there. It's almost the same color and fits flush to the system. But that's my opinion.
It really baffles me how they didn't fix this same problem in both models of system.
And thank you. Hopefully I'll have time to do the model 1 system write up soon.
