Thanks Mark, Gozer, will check out the boards in detail when at a proper computer. Ecc is sounding important for super reliability, though at a significant price. Will do some reading.

Could the Thecus meet my requirements, including a reliable error checking file system?

Mmmm .. not really for the Linux based units, they did have ZFS as a fuse module but it was so bad and slow they took it out.  It does support EXT3/4 and XFS but from memory neither of them have any form of bitrot detection.
The Windows based units (like the W4000) though do support ReFS amongst a heap of other nice things ... price is about $450US ... not bad to be honest! (I only just read about them myself, going to go look them up myself :-)

Finding is fun.
But can you find it again?
And how long would it take you?

Ok I'm home now and can type. Thanks for all the suggestions so far, very helpful they are.

I'm still thinking FreeNAS and ZFS are a good solution for me. Overkill? Maybe, but I have no problem with that. I'd say I'm 70% likely to go that way, with ECC. I'll have a good read about the SuperMicro boards soon, but I won't buy until I have a really good idea about the whole solution.

Seems like I'd need 3 disks for ZFS with 1 parity bit. For 2 bits of parity I'd need 5 disks, which seems like overkill. 1 bit is fine, though I have a bunch of reading to do. I don't need massive amounts of space for my highly protected storage, 2TB would be heaps. I'll use other file systems for less important data - even NFS or similar for stuff I can easily replace. Of course everything will be backed up, but only to NTFS/FAT32 disks. I may go for some kind of incremental backup system rather than the mirrors I have now, which will protect against some things.

Further thoughts are very welcome - how to do FreeNAS, not to do FreeNAS/ZFS, anything really.

How about one of these.

All the reviews I have seen have been great , I would not mind getting one of these myself.

Drobo = NAS for dummies. Downsides including lack of compatibility. As I said in my first post, not interested in DROBO. Thanks for the suggestion though :)

Would be perfect for me then :) , Sorry did not see you mention it at the bottom of your original post.

Currently thinking I might go with
 - SuperMicro X10 1150 motherboard. US $179 (this one is cheaper at $136 but has 5 instead of 6 SATA ports and 2 DIMM slots)
 - i3-4150 dual core (faster than the 8 core Atom) US $119 (can go quad core Xeon for US$80 but unlikely to be worthwhile)
 - 8GB ECC RAM (have to find the right stuff, US$100)
 - A random case from ascent as shipping from the USA is too expensive, $100 say.
 - A decent modular power supply from ascent - much cheaper in the US but probably expensive to ship as heavy. $140.

Total price around $750 for a good server. Kinda expensive given I'll need to spend say $600 on drives too. Any thoughts?

Sounds about right for a decent DIY build.

The question is do you really need/want ZFS?

I tend to think the issue of "bit rot" with traditional file systems is over hyped, a typical 4 bay Ext4 RAID10 from Synology, Qnap, Netgear is actually very reliable.

I do want bit rot protection, as I mentioned I'm experiencing it. I suspect it's drive dependent, not device.

Right now I'm very likely to use Windows 10, ReFS and Storage Spaces with 4TB mirrored rather than FreeNAS and ZFS. If I needed a NAS that'd be one thing, but all I really need is reliable data storage. I haven't really worked out how to do offsite backups though, given I want them to have similar protection - maybe a second mirror but that's kinda expensive.

Ah right just read your other data integrity thread.

If you have the physical room in your current PC... upgrade to Win 8.1 or 10 and add a few new drives setup as ReFS/Storage Spaces Mirorred would be a cheap and easy option for now.

You can always build a stand alone NAS later.

Yeah that's what I'm thinking, my computer can take something like 7 drives. I wouldn't buy 8.1 now with W10 coming along soon, I figure the W10 beta should be fine. Data will all be backed up anyway. Parity spaces sound a bit slow so mirrored with 4TB drives should do me fine - I have an HGST 4TB on the way now, another one coming a week or so later.

Windows Beta is very much a beta, some builds have had explorer crashing multiple times a day. Either use the windows 8.1 enterprise evaluation (90days) for experimenting / validating your proposal, or wait for consumer release of W10.

Good to know, thanks. A friend of mine has it working fine, not with ReFS or storage spaces though. I have no problem buying 8.1, but with W10 so close it would seem to be a waste to buy now and then have to pay again for what Windowss 8 should've been in 6 months.
