Pcix Card For N40L And External Hd Enclosure

Now that I have been running on my new N40L for a month with no issues it's time to repurpose the drives from my old V1 server. All my bays in the N40L are full and I am looking for a good PCIx card and external enclosure for the drives.

I don't need RAID since I am using StableBit Drive Pool. I have been debating the issue of USB3 vs. eSata and leaning towards USB3 but most of the reviews of the matrix controllers in the USB3 enclosures have negative comments on their stability.

What is everyone's recommendations on a card and enclosure?

Thanks...
