Last time I built a PC I almost built a NAS box at the same, but looking at the increase in cost of building a separate network attached PC and the decrease in performance from accessing storage via a LAN I decided to put a RAID array inside my PC instead. The RAID array (on-board Intel Matrix RAID from my motherboard) has served me well and seen me through 2 drive failures in the past 5 years without issue – fortunately the Western Digital Caviar RAID Edition drives I purchased come with a 5 year guarantee with Advance Replacement (Western Digital will ship the replacement drive within 3-5 days, without receiving the faulty one first as long as you provide credit card details). Luckily my Samsung Spinpoint boot disk has not failed thus far!

I recently upgraded my network to gigabit ethernet, so network attached storage now seems more viable, plus I have filled up the RAID storage on my PC (which is probably close to wearing out anyway and I don’t fancy having to find a compatible motherboard to get my data back out again)… ZFS seems to be all the rage these days, and so it seems like hardware RAID is redundant. Some forum research seemed to indicate that ZFS needs a reasonably powerful CPU and plenty of memory, which ruled out my hopes of building a low-power fanless Intel Atom system. Therefore I decided to go with an i3, and the Zotac H55 Mini-ITX motherboard as it has 6 SATA ports.

As for a case, I looked at a few options including the Fractal Design Array R2, the CFI A7979 and the Lian-Li PC-Q08, but in the end decided to go with the Chenbro ES34169.

I also managed to find a Transcend 2GB USB drive intended for industrial use which fits onto a standard motherboard 10-pin USB header to avoid having a USB thumb drive sticking out of the back of the case.

A review appeared to confirm that the ES34169 would work nicely with the Zotac motherboard and an i3. When all the parts finally arrived and I built the system, unfortunately it would not boot. Some swapping of PSUs eventually confirmed that the Chenbro PSU was fine (it would boot a lower wattage system) as was the Zotac board, CPU and RAM (it would boot on another PSU), so the only conclusion was that 120W was not enough for the system.

Fortunately, Kustom PCs were very understanding and shipped me a 180W ES34069 (which has an external power brick) whilst I shipped the 120W ES34069 (which has an internal open-frame PSU, and is not available in a 180W version) back to them.

I had already purchased a low-height CPU cooler after reading the ES34169 review, and this fitted without issue. The only issue I did have building the case was that the SATA cables on the ES34069 were shorter than the ES34169 and two were not able to reach the SATA ports on the motherboard, so I had to replace these with some longer cables. After building the system, initially two of the HDDs did not register with the BIOS. These were the two bays I had switched cables for so I assumed there was an issue with the cables, however after ejecting and re-inserting the HDD caddies the drives appeared.

The ES34069 looks good, the translucent front allows the blinkenlights inside to be visible, which include a power and activity light on each individual disk caddy, somehow magically driven through the backplane (I had always assumed these would need a proprietary connection to a RAID controller).

On booting FreeNAS from a USB stick I initially had an issue with the system hanging whilst trying to load the network card driver, which seems to be a problem with the i386 BSD driver, however it works fine with the amd64 build (which is required for 64 bit support anyway).

So, I can confirm without further ado that the following setup works with FreeNAS 8:

• Zotac H55-A-E motherboard
• Intel i3-550 CPU (3.2 GHz)
• 180W Chenbro ES34069
• 2x 2GB Corsair DDR3 XMS3 (PC3-10600)
• 2x Western Digital 1.5Tb RE4-GP (WD1502FYPS)
• Silverstone NT07-1156 (low-profile CPU cooler)
• Transcend TS2GUFM-V (2GB Internal USB drive)
• Extra 60mm fan (for front of case)

The Transcend USB drive actually took a little while longer to arrive (as scan.co.uk had to order it in specially), so I initially installed FreeNAS onto a USB thumb drive and later transferred it to the Transcend USB drive with dd.

FreeNAS seems pretty easy to use so far. FreeNAS 8.0 is a complete rewrite so unfortunately it only supports basic storage/sharing at the moment, however many more features are on the way in 8.1. Now to copy my data on and start using FreeNAS!

I decided to switch to a low-power Mini-ITX based design rather than replacing the broken motherboard with a comparable one, and after a quick bit of research decided upon an Intel D945GCLF2 motherboard – which is based around the Atom 330 (dual core 1.6 GHz) processor, 2 Gb of RAM and a Morex Venux 668 case from ITX Warehouse. A complete PC (excepting disks) with change to spare from £150 – pretty impressive!

The parts arrived two days later (I ordered after the 5pm cutoff), and within a few hours everything was installed in the new case and ready to go. I was amazed as Debian booted off of the old disk without any issues (try changing the motherboard architecture on Windows without reinstalling from scratch!). After some slight issues with the network I eventually realised the new network card was coming up as eth1 rather than eth0. A quick check of google revealed that the old network card needed to be removed from /etc/udev/rules.d/70-persistent-net.rules. Following this everything was up and running as before.

The fan on the D945GCLF2 is apparently notorious for becoming very noisy after a few weeks, and the fans in the case are of a similar diameter, so I am expecting my next project will be to replace these with either low-noise fans or passive cooling.
