PCS-2 External edition
If your looking for a simple and clean way to power your HTPC on/off via your remote, I would give the PCS-2 some serious consideration.
The fine folks at SIMEREC let me preview the external edition of the PCS-2.
Gotta say they did a great job with it, I like it even more then the internal product.
The internal PCS-2 works very well. However the install involves a little bit of wire splicing, which can be a little off-putting.
The external edition removes the need for wire splicing and only requires 2 connections inside the case and one free PCI bracket.
From start to finish the product can be hooked up in as little as 2 minutes. As an added touch they included a power button with the external receiver.
For people that like to hide their htpc, this effectively give you the ability to relocate the power button to someplace within easy reach.
There is no firm release date yet for the external edition of the PCS-2, but I believe it is targeted to ship before the end of the year.
