    But the 1.5TB WD Greens didn't get good reviews on newegg. Especially for RAID, so the Samsung ones may be better suited.

    yeah there supposed green credentials don't really justify their lacklustre performance compared to other drives imo

Silent, cool running and sturdy. Love them. But you may need more juice if you are going to upgrade your video card later on. Maybe look at a 500W for the frontend. Or use your Antec one.

    Also good would be a PC Power and Cooling one. But there isn't as much selection on newegg.

    Thanks,
    It would be good to know exactly how much juice is needed once I've settled on the components for the FE/BE.
    Then I can decide on PSU's from there...
    I have heard that Seasonic & PCPC are very good from an efficiency standpoint, so they would be in the running.

    I forgot top-end GPU's can suck so much juice!
    Fortunately I won't have it inside the FE all the time, still, I'll need a PSU that can handle it.

    BACKEND:
    What you'd need is something reliable, not necessarily fast. You won't boot the machine often so you won't care much how fast it boots. Even if you got a cool, single plater HDD (most new 500GB are that way now) it should do fine.
    What you won't like is if you'd lose your database with all your recording info. Yes, you would have your video files (on your RAID), but it will be a PITA to rebuild the main HDD.
    True, I don't know why I was contemplating SSD's for my BE's system drive, totally unnecessary. I think I'll use my existing 150GB Raptor & the 1TB Black can be my video capture drive. Hopefully it'll handle up to 4 simultaneous HD streams without issue? Then I just need to decide which 3 1-1.5TB drives to get for storage/BU. I think 3 is the bare minimum, I'm not convinced RAID is ideal, but having 3 gives me options should I decide to go down that road. I have my eye on 3x 1TB Samsung F3's but am interested in others thoughts.

    FRONTEND:
    Probably a much better place for an SSD. I am cheap on the other hand, so I would not put my money there. Just a simple, single platter drive again.

    As well, SSD's are still somewhat of a "novelty" for me (my opinion, mind you). The whole issue with TRIM support in EXT4 still makes me wonder if I want to shell out a premium for them.

    http://www.phoronix.com/forums/showt...t=17243&page=2 - 6 months old thread.

    You can always get an SSD later on and change it in the Frontend. No loss since the recordings and movies will be on the backend.
    Actually I think I'll ditch SSD's and use my old 74gb raptor as the system volume, and for local storage perhaps a 1TB WD black or Samsung F3.

    But the idea is to keep power consumption low on the FE...
    So maybe I should partition the inner section of the 1TB drive for the OS (say 20GB?) and the leave the remaining outer section for local content?

    That way I could do away with the 74GB 10k RPM Raptor...
    But would performance be noticeably slower, or perhaps it would even be slightly better?

    Honestly if I could find a ok 30GB (or less) SSD for the same price as a 1TB WD black or F3.
    Then I'd get it and temporarily use the 74GB Raptor for storage space, or maybe even ditch local storage.

    i would use the 74GB raptor but it's very old (not used heaps over the years) and the sata connect partially snapped off.
    It's possible to still slot a cable in but it doesn't sit 100% firmly.

    Why not the cheapest SSD's I can find as the boot/apps volumes for the BE & FE?
    Or is SSD total overkill for a NAS/MythBE?

    (Sidenote: If you want to experiment a bit, you could go with a diskless frontend, have it boot over gigabit from your RAID on the backend. Mythbuntu has a setup for that.)

    Seems a bit much for what you have in there. Any quality 350W PSU will handle that no sweat. In fact, the closer you get to the actually wattage of a PSU the better the efficiency. For a computer that will be on 24/7 that may matter. But if you have it already, use that.



    1x 4GB USB flash for OS (unsure if this'll be enough room)
    I would advise against using a flash drive for any install you care about. I did quite a bit of testing with them (even tried a RAID 5 over 6 sticks) and they just don't like it much. After a few weeks of working they started to get more and more errors. I guess it's the constant writing that they don't like. So log files and such, just kill them.

    Why not use that 75GB Raptor. With HD that's only a few hours of room anyways.

    For the actual capturing drive I was going to use the black.
    What do ya'll reckon I should use in a RAID5 array for the BE/NAS, WD RE3 1TB or Samsung F3's?
    I think 2TB's still have a tad too much of a premium...
    I do believe that the 1.5TB drives are the best bang/buck right now. WD is a good choice in my books. And the WD Greens will do you quite well. I have 2 in RAID 0 and am getting over 200mb/s. You will never use that throughput on that machine. Even if you transcoded a show, recorded another, and watched a couple recording at the same time, it would be fine. I got 3x 250GB in Raid 0, and they are doing fine with such a load.

    For the back-end I was thinking of doing a minimal ubuntu install & only adding what is needed.
    For the front-end I was thinking of starting the same way and gradually adding MythTVFE, XBMC, Boxee, and maybe lightweight a DE like crunchbang or Lubuntu...
    Why not use the Mythbuntu Distro for both? It's fast, and only what you'd need.

    1x Antec True Power 3.0 650W ........................... [Less wattage possible?]
    Storage Sub-sys:
    1x 1TB WD Black ........................................ [video capture disk, can it handle 4 simultaneous HD streams?]
    1x 150GB 10k RPM Raptor ................................. [boot/system volume?]
    3x 1/1.5TB 7.2k RPM HDD ....................... [For content storage & BU, may not bother w/RAID till get hw controller?]

    ********************************************
    Myth/XBMC Front-end (don't have the parts; cept where mentioned)
    This will be the media player & MAME PC...
    Later (6mth) I'll buy a top-end GPU that'll be swapped-in sometimes for gaming.

    1x mATX H57 or Q57 mobo. ......... [make/model?]
    1x Intel Core i3 530
    2x DDR3 1GB ...................... [make/model?]
    1x 30GB SSD or USB Flash*? + 74GB 10k RPM Raptor? (for local storage; already own)
    OR
    1x 1TB WD Black or Samsung F3? [innermost sectors -20GB?- for OS, outermost for local storage]
    1x Xonar Essence ST (PCI; already own)
    1x H6 (Essence daughterboard; already own)
    1x PSU ................................ [perhaps BE PSU is best here if I intend to use strong GPU sometimes; make/model?]
    1x Case ............................... [make/model?]
    1x nV GT220 ....................... [only if IGP+CPU not enough; make/model?]

    For the back-end I was thinking of doing a minimal Ubuntu install & only adding what is needed.
    For the front-end I was thinking of starting the same way and gradually adding MythTVFE, XBMC, and maybe a lightweight DE like crunchbang etc.
    Interested in peoples thoughts on what I'm missing hardware or software wise or just some general advice.
    Thanks!

    74GB 10k RPM Raptor ....................... [very old -not used much- slightly damaged connector so connection always a bit loose]
    *4GB USB flash ................................ [aside from the fact that 4GB is too small, is USB flash too much of a poor alt to SSD?]
    80GB 7.2k HDD, make/model YTBD.
