I'm planning on building a HTPC sometime next year... I want it to be able to play Blu-ray and HDDVD in 720p. I was thinking about using these things: Motherboard: MSI K9AGM2-FIH CPU: Athlon 64 X2 5000+ 2.6 GHz RAM: 2 x 1 GB something HDD: WD Caviar SE 16 500 GB Cabinet: Origen AE H7 PSU: ? HDDVD: ? Blu-Ray: ? I'm a noob when it comes to these things, so any help will be much appreciated. Do I need anything besides the aforementioned stuff? How good will HD/BR playback be on a HTPC like this compared to standalone-players?
