external enclosure for raid array

What do you house your raid array in? I want to have an 8-disk array but I don't have room for that many drives in my computer's case, and I don't really want to have a single huge case. What I'd like is an external enclosure that can hold all 8 of the drives and connect to my computer via e.SATA. That doesn't seem like a difficult concept, but I'm having trouble finding what I need.
 
Here you go.

Note that it's $500. You're almost certainly better off price-wise with a large case, but there's what you asked for. It uses 2 infiniband connections, which will work with almost any external-oriented sata card.
 
wow, that one is expensive. I found this one for a little over $200, which is much more reasonable for me.

It comes with a power supply, but I wonder if I should immediately put in a better one. Since I'll be running RAID 5 I really don't want a double drive failure, and it seems like the easiest way to get a multiple drive failure is from the power supply. Does this sound reasonable or am I being paranoid?
 
A computer power supply may be crossloaded by running a load with approximately equal +5 and +12 requirements and no need for +3.3, like hard drives. Thus, replacing the power supply may not be as easy as it sounds.

The reason for the cost difference is probably the hotswap bays, and may also be because of case quality. Also, the unit itself is smaller. Just something to consider.

 
No, they've got hotswap caddies. You screw the drives into them, and then you could remove and add a disk without powering down the machine or the array. That makes it easier to swap out a failed disk under load conditions, or you could leave one free slot for a backup drive and be able to swap it easily. That's pretty much the only advantage (other than possibly build quality - but notice I haven't used either of these ;)).

 
i've used a type of these and they work pretty well for what I thought I wanted to do. They were firewire but you'll be doing eSATA but really it's all about if you want to do raid 5 on the device itself or on your own computer.
 
oops, on my last post I meant to ask if they have special PSUs not harddrives :p

Also, I was just planning to do raid 5 on my computer with probably a Highpoint 2322 card.
 
I don't know if they have special PSUs or not. Could be either way, but my guess is not. If you decide to buy one, take pics and post 'em :D
