I hope this is the correct forum to ask my question since its a storage rig I want to build. I have two HP Microservers with 4 x 2TB drives in each, an external esata 4 bay hardware raid caddy with 4 x 2TB drives, an 8 bay esata enclosure with 8 x 2TB drives and multiple other smaller capacity sata scratch drives I use for moving stuff around using a dual dock. Each has 8GB of ECC ram running Win 2008R2. I also record to them via two IP cameras for security. I want to eliminate all of the power plugs, cables, flashing leds and if possible the noisy fans to try and put together a decent home server which will mainly act as a NAS streaming video to several media players, with two possibly three VMs running on it. One for WHS2011 to do client backups, one for W7 for usenet downloading, torrents etc and possibly one to act as a testing ground for any new stuff I feel like playing with. So currently my microservers handle all of this nicely while being relatively low on power consumption. I'd like to build a replacement server to house all of the drives and handle the VMs but still be as low power consumption wise as possible. In the microservers I also have a HP410 hardware raid card and a highpoint 2680 raid card which I currently use for raid 5 sets as well as a software raid solution FlexRaid. I may or not use any or all of these solutions in the new build. Im open to all ideas. Where Im lost is in the selection of the appropriate psu, motherboard, processor and ram to accomplish these goals while keeping power consumption as low as possible. Its been many years since I last built a system so am not uptodate with all of the available hardware choices. I want to put all into a full tower case maybe something like the Lian-Li PC-D8000 when available. Can anyone advise me on the best hardware to accomplish this goal? Many thanks for taking the time to read this.
