I just bought a new HDD and I am out of room in my case for it. I am planning on getting a 3x5.25" bay cage for 5x3.5" HDDs but am also out of sata ports. I remember seeming a cage that have a built in port multiplier but can't seem to find it. My motherboard only have 4 sata ports and I have a 2 port expansion card that is also full. I know it supports port multiplication. Are there any out there our should I go another route?

Also search the forum for port multiplier. Sorry, using my phone.

Thanks I couldn't find what I was looking for there. I am looking for an internal cage. I will look on the forums some more.

There are several small EXTERNAL cases that come with built-in port multipliers.  Here's an example:

But I'm not aware of any internal units like this.  I'd assume that most manufacturers simply assume that if you're using an internal unit, you either have sufficient SATA ports, or will simply add a card to provide more.

 

Alternatively, you could simply replace your 2-port card with a 4-port card.

 

Something like this if it's PCI:  http://www.newegg.com/Product/Product.aspx?Item=N82E16816124024

 

or this if it's PCIe:  http://www.newegg.com/Product/Product.aspx?Item=N82E16816124027

If I a 5 slot cage to max out my case then I will need 5 more ports. I will either just get a separate port expander or a sas/sata card but can't find one with PCI-express x1.

You're not going to find a card with more than 4 ports that's only PCIe x1 => that's even a stretch for a 4-port card (it clearly can't sustain max bandwidth for 4 modern 1TB/platter drives).

 

The PCIe x1 card I noted above has 4 ports.    It would be a good choice for one of these excellent 4-in-3 cages:  http://www.newegg.com/Product/Product.aspx?Item=N82E16817993002

Couldn't I get away with this card instead of the one you recommended?

Sure.  It's a Marvel vs. a Sil chipset, but otherwise they're essentially the same.
