Need advice on getting a mobile rack

[Nitemare]

I'm planning on getting a mobile rack(so that I can exchange hard drives or pull one, hot swappable isn't necessary)

I wanted to stay around the 30-35 dollar range and needed something that would cool as well. Anyone use any and can I get a recommendation

So far I am looking at getting this one..

Kingwin KF-22

It will be for an ata133 ide 7200 rpm hard drive and can't find that many units that will do ata133.

Thanks
