The PBO accepts a standard 2.5" SATA hard drive or SSD which can be installed as an option in order to store media files locally. It's not required however if you want to save custom playlists or access and download BitTorrent or Samba file sharing you will need one. I've installed a spare 250GB Hitachi drive here for purposes of this review.
Patriot sent along their wireless-N USB adapter to test out with the PBO, although they claim most third party adapters will also work. The one problem I noticed with this adapter is that it doesn't fit well into the rear USB port of the PBO as the lip of the case interferes with getting the card pushed in all the way. The front USB jack does not have this problem however and the card is small enough that this doesn't look bad, however it may block line of sight IR signal from the remote in some instances.
I'll be using the PBO with the wireless-N adapter to stream multimedia files from my server, which is connected via Gigabit Ethernet through my Linksys WRT310N wireless-N Gigabit router. Wireless-N theoretically allows for up to 300Mb/s bit rate, and coupled with the server's 1000Mb/s Gigabit connection should allow plenty of bandwidth for streaming even full 1080p.
For display I've connected the PBO to my 40" Westinghouse VR-4085DF LCD television. Supporting up to 1080p at 60Hz via HDMI this should test the PBO up to its maximum output capability. Using the recently reviewed LG Blu-ray drive I've gone ahead and ripped some HD content to my server to test with.
Let's power up the PBO and have a look.
