Is this powerful enough to meet my goals

[Hunter69]

I currently have a WHS HD sagetv server. I record HDTV via collossus X2 and HDhomerun.

I am thinking of changing things. Here is what I am shooting for:
1. I am building a Home Theater with a projector. I am wanting a very visually appealing Movie streamer.
2. I want to keep sagetv. So I am thinking of changing my sagetv server to a WIndows 7 pro operating system. Sagetv is served up to HD200 X2 and 1 HD300.
3. I am looking into XBMC as my movie streamer due to its very visually appealing skins.
Now for the Hardware:
I purchased a I3 2100T, 60 ssd drive and 4 gig of ram. Will this hardware be powerful enough to run sagetv and stream blurays simultaneously. Sagetv will not be used to stream movies only serve up content to the sagetv extenders. XBMC will serve up mkv bluray movies.

Thanks for any help and suggestions.

I don't understand how you'd be using XBMC in this configuration with the HD200/300 extenders, but it seems that you could do all of this within SageTV without any problems. The Colossus has a hardware encoder, and the Sage extenders have hardware decoders, so the CPU would be pretty trivial. OTA HD signals are just mpeg data streams that are written to the hard disk. Any HDD of ATA-33 or higher can write fast enough. It does not seem that you would have any trouble capturing and streaming to your devices ...
