does anyone know of any external hard drive enclosures that have space for 2 to 4 hard drives. my motherboard (a8n sli-premium) came with a neat little slot add-in card thingy that can allow you to connect two external sata hard drives outside of your case, and i figured in stead of using them for just hot swaps, that i might be able to make a nice external raid setup. maybe two 500 gig hard drives in raid 0? tempting, but i would need an enclosure for them if i wanted it to be any reasonable sort of setup. any ideas of specific products or just where to find them would be nice.
