So far I haven't been able to find any 1U NAS turn-key raid solution for anything under $2000 for just the chasis! So this thing is going to have to be hacked together, and this is what I've come up with:
1 EPIA MB w/ VIA C3 800mhz Processor (mini ITX) A tailored case [ likely out of a tape deck ]
You might take a look at http://www.linitx.com/ . They have a number of cases.
Will the performance of a linux software raid level 5 be sufficient w/ the VIA C3 800mhz Processor?
It should be, yes.
Will the data be safe under LSR? ie. If a disk dies, will I be warned?
If you set something (mdadm, for instance) up to monitor your raid, yes.
When I shutdown & replace the disk, will data remain?
Yes.
Am I better off using a 3Ware Escalade or a Promise FastTrax SX4000 to handle my array?
If you have the cash to burn, HW raid is a bit easier (IMHO) to use. I have nothing but praise for 3ware's controllers (well, except for RAID-5 write performance).
Will I have to have a 4th HD to boot off of.. or can I create a custom bootable CD that will bring up my system (kernel, raid, apache, nfs, samba) ? Or should I boot directly from RAID?
You can boot from RAID1, so you could create a small RAID1 set, to boot off.
