I have Fusion 8HD Klaus Schulze Edition. It was almost unused many years because I left it to my parents to wait that I get enought room for it. Now I put it to my masterkeyboard, but now I remember why I didn't put it masterkeyboard before, allthought I really like its key-feel..because hard disk and fan noise.
Hard disk noise will be gone anytime soon, because I put IDE CF-card reader in it. And I think that I can do something with that fan noise too, but it seems to be hard and expensive solution.
