eventually you'll come to realize what i'm trying to say. HDD powered up inside the machine cause alot more problems then most people realize. aside from the heat and noise factor (it becomes a factor when you are talking about that many drives), the wear and tear on the drive can eventually cause data loss. mechanical drives response time can also occasionally cause BSOD depending on what data/program you have installed on them. it's also additional work if you ever get infected with virus/malware regardless how well protected you may think you machine is. as for portability, the additional weight of the 5 drives will definitely come into play if you intend to make it a LAN party machine.
alas, it's not my box and you're the one who has to live with it:D I'm perfectly happy with the FT02 since my schooling days are long behind me:D
