Turns out that thing sticking out the back is just the clip to lock the cards.
Anyway, I've kinda gone off this case since I found out the PSU filter (and the one next to it) are inside the case, so you'd have to remove the PSU to clean the filter! I guess I could just take the filter out completely, but then dust/hair is going to get sucked into the PSU, which doesn't seem like a good idea.
I wish they'd put the filter on the outside, like with the Rosewill Challenger http://www.tomshardware.com/reviews/nzx ... 723-9.html
I think front facing power/reset buttons would be better as well (cat might sit/press on top mounted ones), like on the Casecom 6788, which also has the clips for the filter like the Rosewill, but doesn't come with a filter, although maybe it's easy to buy one that will slide in there http://forums.hexus.net/chassis-mods/17 ... w-pob.html
However, this doesn't have a hinged door (you have to pull it off, which is a bit dodgy and I can see my brother breaking it), nor does it have a removable filter for the front fan, unlike the Silverstone:http://www.overclockersonline.net/revie ... chassis/4/
So I'm still looking for a case with:
front facing buttons
4 5.25" and 1 or more 3.25" external bays (although I could probably make do without any 3.25" bays if I have to)
external PSU fan filter (if bottom mounted PSU)
hinged door and removable/cleanable front fan filter
either vibration damped HD mounts or removable drive cage
If I can't find anything suitable, I'll have to keep modding this old case I've been working on instead. It'd be less of a pain if I hadn't lost the motherboard standoffs (which were 7.5mm, not the easy to find 6mm)! It's only got a bottom intake fan (PSU at top) and I'll need to put a removable fan filter on the outside but I think I could screw something like this to the case and then the other part unclips (would need to be done without tilting the case) to remove the filter http://www.ebay.co.uk/itm/Dustproof-120 ... 3463wt_952
