Hi Wave Ace,
I'm assuming that You need the low profile to put into a HTPC case or Mini ITX case.
Does the case have existing slots for low profile cards or is it a custom install.
The reason I ask is that You may be able to use a Mini ITX PCI riser card which will mount a PCI card above the motherboard, or if You have space , away from the motherboard (which may make the cooling better as the cards get hot!!).
You would only need to cut the rear panel to allow the CAM to be inserted and leave access to the f-connector for connecting the cable.
Also if You're using it for a HTPC , have a search around the net as there are not too many programs that support DVB-S cards (whereas all seem to accept the DVB-T cards).
Hope this helps You in Your quest,
Cheers for now,
Old Geezer
