FYI, others can't view your newegg wish lists.
Hardware shouldn't have any issue with 1080p playback.
On the HDAV, you do have a DTS-MA and TrueHD capable receiver? If not, its unnecessary and you can use the on-board SPDIF.
You may have issue with the wireless from the server. Not because the wireless can't handle the throughput of a 1080p video, but because wireless can be unpredictable and volatile and you can lose packets causing them to have to be resent, which equals skips and hiccups in a streaming video.
