Ok, no one answers you. I will. for one build idea, see my sig: Mini-HTPC or something similar to what I describe below, then see Captain Slugs
Project Remora in the Project Logs, Excellent work!
My experience: I have built several and now take the easy route (too many TV's). I know mine is not done yet but it is operational at the time.
To max your capability, you will need a mobo and processor of at
LEAST 1.8Ghz. You probably could get by with something less, but it is not recommended.
next things- minimum required hardware:
Any case will do, but most people want something attractive and blends with the furniture.
256Mb Ram, best is 512Mb or 1GB
DVD Rom
TV Card - WinTV-PVR-150MCE or WinTV-PVR-250MCE, either one is good, there are several at
http://www.hauppage.com/Pages/prods_pvrs.html#MCE. As long as you get one with hardware encoding your are good as gold.(Edit: Newegg usually sells them Cheaper) nearly everything at Hauppage will work with any good Media front end you want to use
Video card - My preference is Nvidia video cards with TV-out and minimum 128Mb RAM. you dont have to have the biggest fanciest for TV out unless you have Hi-def, then you will need to change some hardware.
I have one set up that way but don't expect to use a monitor and TV unless the specs & drivers will allow. Most of the time you get one or the other
Last and probably most important. Storage. I use anything over 160GB for recording and storage. I Recommend is 250Mb.
a Really Good PSU, 480W or better, and an OS.
I use Windows 2000 on everything and for Television functionality, I have Snapstream (not a free software). there are many out there. Nearly all of them are listed with Hauppage with their Media Center Edition TV cards.
If you have any questions on this feel free to PM me, I may be a couple of hours to answer, but I am almost always around. (no kidding-like a Ninja Stealth Forum Freak
)
