Using 80gig drives I get about 800gig ea. @ level 5 in a relatively compact box. They have a space in the upper rear that can be easily modified to hold an extra 4 drive bracket, the same as the one used in the front of the box. If you wanted to drill some holes, each bracket could be further modified to hold an extra disk for a total of 13. The power supply puts out more than enough to spin up eleven 5,400 rpm IDE disks at once. The cost and reliability is good, though at RAID 5, I/O is low and CPU load high but acceptable for what I use them for. Heat is acceptable with the lower speed disks, the 420 is well ventilated, but I attatch an extra fan to a convenient spot on the back anyway for extra cooling. I have three of these in production under substantual load and haven't had any problems with them yet. Which filesystem do you use? (If it's ext2, how long does an fsck take?)
