I STRONGLY suggest looking at other options. QLogic makes some really shoddy products and charges way too much for them.
A few years ago (before I was enlightened on the advantages of doing your own work) I ordered a QLogic box. Several of the seams were leaking air, resulting in horrible sound quality. I returned it, then returned the replacement. After 3 peices of crap in a row, I decided not to deal with them again. They are also really ugly, but that's just my opinion.
If you really want one cardomain's price is inline with other discounters.
