Hi, i plan on building a new HTPC with a sweetspot and xcard using Dscaler. I want it mainly for scaling DVD and Foxtel Digital (Australia) to a HD plasma, PVR, and music playing. Can i get some hardware suggestions for uncompromised performance? 1) CPU & Mobo. I was planning on an Asus A7NX-Deluxe with Athlon XP 2100+; will this be enough or maybe even overkill? 2) Ram. I was thinking 512MB of Dual channel DDR 333 or 400Mhz. Is memory speed especially important in a HTPC such as mine or for other HTPC setups; how so? 3) Hard disk. In my HTPC I will use one fixed HD for XP but also an external removable HD which i can use for PVR. The external Hard drive should have enough space to record at least a couple to several movie length shows using showshifter. It can be modestly sized because i plan to transfer the drive to my P4 2.8C with 80GB which i can use to compress files and/or burn to dvd etc. Please let me know how big my external HD should be or just how many MB are used when recording an uncompressed movie length show to hard disk? 4) DVD/CD drive - Just a quick and probably silly question, but is a DVD-ROM just as good for playing back audio cds or will a CD-ROM only drive do a better job? Thanks heaps.
