thank you all for the ideas, they're all great.
Gondola71 you're right, I was thinking the same about the "short life" of the flash card.
I don't want any HD, the whining noise is killing me. And I'm sure in 1-2 years, maybe sooner, a new one will start to do the same thing.
bfonnes, I thought about that too and I do have a PC in another room that runs almost 24/7.
Aflac, I'm not using it that much, my wife does. She's a student and she uses it for internet and word processing. I would like to remove every fan and use a pasive or a water cooling solution. The PC is a P4 Northwood at 2.4Ghz, not overclocked, 512MB RAM RDRAM and a nVidia video card that already has a pasive cooler: Zalman ZM80D-HP.
Nocturnal, it's not the read\write noises that bother me, but the whining.
