can you run the expander like that - not plugged into slot?
yup - thats what the power plug is for

i have an sff-8087 to sff-8088 pci bracket coming from ebay, also i bought another sff-8087 to 4 sata cable so i have the option of running 20 drives for now and the option for saisy chaining 2 cases.
speaking of which how do you turn on the psu in the second case when you daisy chain??
that would be sweet to have tiny little case with small mb and all those drives
As long as you plug in the power cable.
He has it in both ports 1 and 6.
His raid card only supports 1 cable though.
And this also means 4 drive bays aren't plugged in.
I'm somewhat surprised that with large numbers of drives, people don't seem to be guarding against container / backplane failure. For instance if you have 3 backplanes each of 4 drives, you could RAID 5 with one drive on each backplane, then stripe across for a RAID 50. Then not only would you be protected for one drive per RAID 5 segment, but you'd also be protected if one whole backplane failed. I've seen this done with backplanes that are a full rack-width. If you had 4+ backplanes, you could use RAID 60
How often does a backplain failure also destroy the drives?
Seldom, but a backplane failure will remove a group of drives all at once. Which would make your storage unavailable. Effectively you're RAIDing the backplanes.
The drive just going offline is extremely easy to fix on areca controllers. I have external storage which is not on a UPS sot he computer was still running and all 30 disks went offline at once and it came back up without me doing anything but even if it didn't automatically come back up its still an easy situation to recover from.
But suppose you had 3 banks of 10 and 1 bank - 10 disks - went off line but not the rest. One failure has cost you 10 disks.

RAID is never, and will never be a replacement for actual backups. Data stored on an array should simply be the live copy, not the only copy because RAID is not a backup its just for redundancy and performance.
