Suggestion for external enclosure for 2 HD's in RAID setup

[BlueHeelers]

I have the Iwill ATA 66 RAID card and 2 IBM 45GB HD's. My problem is the hard drives generate a lot of heat and I would like to put them in an external enclosure as my Thunderbird generates its own share of heat. Does anyone have any recommendations for putting the harddrives in a single box or enclosure?

Thanks
