Acer AX1301-U9032 for HTPC/media server?

[heat23]

Fry's has a deal on this Acer AX1301-U9032 PC for $300 this week and I was thinking of using this as a HTPC. What I plan to do is connect the HDMI to my receiver->TV to watch DVDs, listen to music, etc. Also, I want to hook up a 1 TB+ external drive to use it as a media server/NAS (w/o raid). Any opinions on this computer? I am deciding to buy this or build a PC (only if it is cheaper)...

Here are the specs for the Acer:
