2 System Raid Setup Reccomendation

Hi Everyone! Currently I have a dual boot/bootcamp Mac that is connected to an old Ciprico Raid, that were using with a Kona3G card that works fine on both OS'es. For a variety of reasons I want to buy a separate PC box and reformat the mac box to be mac only. The problem is, I have no easy way to connect the two systems to the same raid in the configuration/hardware it's in now (ciprico went out of business).
I have 8 drives totalling 4 terabytes that are still perfectly fine and speedy, so I'd like to find a different chassis that I can put them in (that still holds up to 2 streams of 1080 60p playback) in an attempt to hopefully save a little cash so I don't have to purchase a brand new case AND drives. Does anyone have any recommendations for something that would fit the bill?
(One last note, it's highly unlikely i'd use both systems to hit the raid at the same time, it would be one machine or the other)
thanks!
