Then try a cheap Silicon Image SiI-3114 controller (4-port) or 3112 (2-port) these come in about a thousand different brands, all carrying the same chip and drivers, essentially being the same product. It should cost about $15-20, and could be a solution to you.
You would need to use their sucky RAID drivers under Windows, creating a RAID array for each disk. It wouldn't be stable, it wouldn't be reliable, but it should work and if you want something quick it may be suitable. I wouldn't invest too much in older systems though; for 200 euro you have a brand new system already, but $20 should be okay i guess.
