Think this post would have been better off in here... 
When I bought a laptop, I built an HTPC out of my old desktop computer and, realising that there wasn't a do-it-all board, decided to use what I had and just stick it in a nice case (Silverstone LC17), but with a full ATX board and a HUGE graphics card, the case it pretty rammed and I haven't been able to get all my hard drives in. This is what I ended up with...
Motherboard: Asus P5B-E Socket 775
Processor: Intel Core 2 Duo E6420 (2.13Ghz) Socket 775 FSB1066 4MB Cache
RAM: Kingston 2GB KIT (2X1GB) DDR2 667MHz/PC2-5300 CL5 Non Ecc 1.8V
Graphics Card: Gigabyte 'Silentpipe II' Fanless NVidia GeForce 8600GT 256MB Dual DVI PCI-E (GV-NX86T256D)
PSU: Hyper Type-R Modular 580W
CPU Fan: Zalman 7000B Alcu (with Socket 775 Adaptor)
Drives: 4x SATA Hard Drives (only 3 fit in for now!), 1x SATA LG GGC-H20L Blu-Ray/HD-DVD/DVD-RW, 1x IDE DVD-RW
What I'm now considering is replacing the motherboard and graphics card with this Gigabyte GA-E7AUM-DS2H, giving me much more room in the case, or perhaps even going for a smaller case (but given that I need at least 4HDs and 1 optical, perhaps not!)
Just wondering if this would be a good buy as I'm looking for something that will work with my current setup and also with any likely/foreseeable future upgrades.
I'm currently connecting to a Sony STR-DG910 by HDMI and optical, which is hooked up to a 5.1 speaker system and a Screenplay 7210 720p projector. For now, I have to use optical for the audio (7210 is DVI, not HDMI, and if I send sound via HDMI from any source to my amp, as soon as I switch the projector on, it kills the sound). I think my next upgrade would be a 1080p/24-capable projector, which this board would be ideal for, and that would then let me switch to HDMI for audio too.
My other issue with my current kit is that it doesn't sleep/hibernate (it'll go into these modes but not come back) and, really annoyingly, that I have to have my amp and projector on when I boot my HTPC or I can't get an image from it, no matter what I do. No idea if that's the computer's fault but I don't get it with any of my other sources, so I'm really hoping that a new mobo (with integrated graphics) would fix this...
I realise that's a lot to dump on you in one go, but can anyone foresee any problems with what I'm wanting to do, and with the kit (RAM, CPU, fan, PSU, IDE DVD-ROM) that I'm planning on plugging into it?
