Looks pretty much as I was expecting, thin plastic sheet with holes punched in an off set honeycomb pattern.
In theory these sort of filters could work well, the issue I have with them tends to be to things.
1 the material to hole ratio, all filtering system add some air flow restriction, I've seen one of this type of filter where the amount of material between the holes is so large that the overall hole area must of been 30% or less.
2 the size of the holes, if the holes are too large then they are not going to be stopping much, eg the filter in the new coolermaster elite 120 is pretty pointless http://forums.hexus.net/chassis-mods...ni-review.html (why yes I am linking my own thread ) with each hole at ~3mm diameter it's not going to be catching a great deal, it's going to be more of a large fluff & hair screen than a dust filter.
Foam filters tend to be good but they are more of a pain to clean, ideally you need to carefully wash them, you can damage the foam easily if you're not careful, then press them dry between multiple bits of kitchen roll to remove the excess water and finally leave them to air dry for a while before returning them.
The other common filter is a mesh screen filter these are a simple sheet of open weave plastic or wire mesh fixed in a plastic or metal frame, commonly plastic is used and it's heat treated to melt the separate woven strands together to change it from a woven material into a single sheet.
a screen filter can suffer the same issues as I've mentioned for this new type, which is basically a screen filter, however in most normal screen filters found in PC's the holes are around 1mm and the strands are well under that, at a rough estimate I'd say 0.25mm, that is a heck of a difference compared to these new ones both in terms of hole size and material to hole ratio.
Compared to a foam filter, the more standard screen filter isn't quite as good, it'll catch small fluff but it'll not catch as much of the very fine powdery dust as most foam filters do, however cleaning them is far easier and they are more robust than foam.
You've also got the DemciFlex filters http://www.demcifilter.com/ these are just a screen filter but they are using some really fine medical grade mesh that will catch most of the really fine particles as well.
@phill8800GT,ebay is a great place for short sata cables, I've ordered a couple of these ones http://www.ebay.co.uk/itm/190691487307 there are places selling cheaper and shorter cables, I went for these ones for the locking heads, one right angled head one standard head, not stupidly expensive and the black round cable should look good too.You could probably find 15cm SATA cables but I'm not sure where the cheapest place would be as most places charge delivery. Might be worth checking places like eBay, Amazon or Kikatek.
