Hi, I just bought a Hitachi PJ-TX200 Projector and have it set up in my office where the PC (dell 8400 - 3GHz, 1.5Gb RAM, ATI 9800 XT) is. So I thought I'd plug in my PC and see how it goes for watching TV / DVDs. It is pretty noisy though so I thought about rebuilding it and making it quieter (new quiet case, psu, and graphics card) so that when I watch films it does not bug me. After I looked up the components I might need it all totalled nearly 300 quid (SilentMaxx case, quiet PSU, 6600GT passively cooled). Then I looked on Dell Outlet and saw a 5150 for about 300 quid. So it got me thinking. Is it just worth buying a new PC for the same price as some people here report the 5150s are very quiet? 300 quid seems like a real bargain. So here is the spec: Pentium 4 630 (3Ghz) Operating System: Genuine Windows® XP Media Centre Edition 2005 Memory: 512MB (2 X 256, NON-ECC400MHZ DDRII) Hard Disk Drive: 160GB 7200rpm SATA Hard Drive Video: ATI Radeon X600 256MB HyperMemory Modem: V.92 Modem Data/Fax/Voice PCI UK DVD Drive: 16 X DVD +/- RW I would pretty much like to watch DVDs through my PJ on it. Possibly using Theatertek and using other neat tools like FFDShow and DScaler to upscale my Sky+. So I'll need a capture card and there is the bonus that if I feed the SKy into the PC I only need a single DVI-HDMI cable going to the PJ. Also I'd use it as a DVD Recorder. The odd game would be good however I have a gaming PC for that. So here are my questions: - does anyone know how silent the 5150s are? - there are some available with X300's which I think are passively cooled however will the fan noise of the X600 be significant? Can you clock the fans down during movie playback? - how can I hook up my Denon AV2801 amp? It has digital coax and optical in ; what soundcard would be viable? Thanks for your help, Spencer.
