Hey all. I'm a new owner of an Apple TV 2 after owning iPhones and iPads for some time now. After purchasing the Apple TV 2, I'm looking to streamline my media setup and how I stream to the device or any other device in my home for that matter. I'm looking for some opinions from seasoned users of these products. I have a year and a half old HP desktop I purchased on Black Friday. It's a decent rig for what I use it for, 1 TB HD, 8 GB ram, AMD quad core CPU. I upgraded the graphics card to a 9800 GT for a decent price for some light gaming (namely Diablo III coming up). Runs Windows 7. I have a old (~ 6 years old) PC running XP sitting in a closet. 1 GB of ram, onboard graphics, ~1.4 Ghz P4 (I think). Small HD. My first delimma is I have no backup capabilites for any of my media. Everything is stored on the desktop and not backed up anywhere. My first child is now 1 year old and 1 year's worth of baby pictures are invaluable! I need to do some backup! Adding some sort of RAID 1 setup is a must. Lastly, I'd like to finally become a Mac owner. With an ATV 2, iPad 2, and iPhone 4 (soon to be 2 iPhone 5's) it's the next logical step. I don't hate W7, but I love Mac hardware and OS X. Lion looks fantastic. I have several options to serve my media server needs and possibly quench my thrist for a Mac. Option 1: Continue to use HP as primary desktop and convert old Dell desktop to media server To do this, I would likely need to purchase a new, quieter power supply along with a RAID SATA controller and 2 1TB HDs, along with an ethernet switch as I'll probably access the same RJ-45 port in my bedroom. The intent of the sever will be media serving only, but hold my entire Itunes library to feed my Apple TV and pull media to put on my iDevices. It will be hidden and have decent airflow, but no direct access. I can remote into it to manage files, etc. with Splashtop on my iPad. Questions: If using this setup, can I access the Itunes library on this computer using my normal desktop? e.g. Can I place files on my iPad using Itunes on my normal desktop but the files are on the server PC? Also, for converting media, would you recommend ripping DVDs on the normal PC and moving them to the media server to Handbrake, or ripping and Handbraking on the normal PC? Option 2: Use primary desktop as media sever I already have a 1 TB HD in this PC, though it's a 5400 rpm drive. I would likely still need to purchase 2 drives and I would need to purchase a RAID controller. This PC is in our bedroom and quieter than the old guy, but still a little loud and power hungry to possibly run 24/7. Option 3: Purchase Mac Mini and external (Firewire?) RAID 1 Enclosure This is the most expensive option but perhaps the most elegent. I would now have the Mac I always wanted and would likely be a little smoother for the light home movie editing I do. The Mini is fairly low power and quiet, correct? If I use this setup I now have 2 PCs in the closet and my primary desktop is on 24/7, though I keep all my media in one spot and it's backed up in the RAID enclosure. Another kicker is Plex. Currently I'm Handbraking all my movies to Itunes, but what is the advantage of Plex? It is nice to be able to stream any movie format, but the disadvantage is the server has to transcode. I imagine if I used the old PC as a server, it would be too slow to transcode, but the Mini or my current desktop could handle it. Thanks in advance for any advice and opinions!
