What should I use my Studio Display with?

Hey folks. Just got my hands on one of these babies:



Zippity doo dah day-- the Studio Display. $20 bucks at my school rummage sale. No one bought it until I came along. (My school is Microsoft-sponsored.)

It's an external display. It'll only work with my Thunderbolt Mac with 3 third party adapters. Should I use those or get a PowerMac G3 system?
