Sure, you could get the Antec separately or an Enermax (or whatever other brand you like, there are a few high end manufacturers). The case chassis is the same, like I said. All versions that are available from Antec are available from Chieftec. If you type "Chieftec" into the search box at Newegg you'll get quite a selection.
