1. The case is highly subjective and personal. I use a Silverstone Crown CW02B for my HTPC, it is rather expensive @ $365 when I purchased it. Primary reasons why I bought it:
- a) It has 6 drive bays, and one for an optical drive.
- b) Uses 120mm fan, generally large fans can move the same amount of air as smaller fans using less RPMs which means less noise.
- c) Thick aluminum to help suppress noise.
- d) Mounts for optional 92mm fans to cool hard drives
- e) Very compact case which can fit a full size ATX motherboard (makes building rather tricky)
- f) Lack of a power supply means I am not wasting money on some average PSU. I can drop in my own high quality PSU (Seasonic S12 500).
2. This my current hard drive set up:
- a) Somewhat used E-IDE 160GB Hard drive for Windows 7 Premium (currently evaluating it for 30 days trial period). Partitioned into 40GB drive for the OS; remainder is for logical drive just to store data / potential games.
- b) Two SATA 1TB Western Digital Enterprise Class hard drives in RAID 1 mode (mirror) to back up data. Audio files (mainly FLAC) and Video files are stored on these drives for "permanent storage". Only full encoded files are written to these drives. Potentially these drives should be access / used the least so they should last a long time before requiring replacement.
- c) SATA 500GB Western Digital hard drive used to rip DVDs (Blu-Rays later) for encoding into MKV files using X.263 codec (used DivX in the past). All encodings (audio & video) are done on this drive, once completed files are immediately transferred to the mirrored 1TB drives. I also set the windows Page file to use this drive. I refer to this drive as my "THRASH DRIVE" since this drive will be used the most due to constant writing and deletion of data (ripping & encoding), thus this should be the first drive to fail.
- d) Two available drive bays for another RAID 1 setup in the near future.
3. Generally no if onboard video is good enough. I prefer using a discrete graphic card, got a passively cooled 9600GT in my HTPC.
4. Current tuner cards cannot decode copy protected stations. Therefore you will have to manually set the tuner box to the channel you want to record. ATI's upcoming TV Wonder Digital TV Tuner should allow you to record protected stations if Time Warner is supported. You should expect this product to be a bit expensive; $200 - $300. You will most likely still need your cable TV service. Product link:
