On cable management, I found my Seasonic S12-430 cables too short for 'behind the tray' routing to motherboard power and optical drives, but it's a handy place to hide the unused cables (though I had to bring the end connectors back in behind the upper drive cage to get that door panel to close.) The used cables were all routed through the semi-circular cut-out at the door side instead of through the sliding cable doors, giving less central congestion and easier air flow between two drives down there and the PSU fans. The cable-door gaps are sealed, as are the back-panel holes round the PSU.
A single low-power case fan (Yate Loon @ 7.3V) is installed, on the back panel. On the top vent, smoke testing showed it was sucking air into the case, short-circuiting flow from the front; however, blocking the top vent put CPU temps up 3-4C so I've left it open (the supplied Antec fan is still mounted but unused, with its wires hidden away behind the tray) .
System is an undemanding Asus A7N8X-E-dl, Sempron 2600+ with Arctic Silent 2 TC, passive FX5200 graphics card; no problems but the thermal fan on the Arctic is running faster and case and CPU temperatures are a few degrees hotter than with the last case (Antec 3000B) which had similar fans both front and back. I'd like to get more air past the north bridge and graphics heatsinks, so may add another fan to the upper drive cage position. As it is, I've left the back slot cover under the graphics slot un-blocked to encourage air to come in and past its sink.
Compared to the 3000B, it's noticeably quieter, mainly due to less HDD noise; I had an irritating pulsed vibration from the two drives interacting, gone now with the P182 suspension system, its sturdier cage construction and tighter plastic slide mounting.
I'm well pleased with the case - little touches like the filter door catches, the soft clunk of the door as it closes; a touch of class.
