During installation, I did not run into any problems though there was one major thing I was not a fan off. When looking from the back side of the motherboard tray there was what appeared to be a hole to pass through a 4/8 pin EPS connector but as you can see, when a normal ATX board is installed the hole is not visible from the front. Now, you could go ahead and pass your cable through before installing your motherboard but this is just something I personally do not like to do though I have done it in the past.
Aside from that and having to route the EPS cable across the motherboard, everything else was smooth sailing and the PS11B-Q was a pleasure to build in. There were plenty of pass-thru holes for cables in the bottom by the PSU and going up the side next to the motherboard. Everything seemed to fit right into its place and I did not notice any space restrictions and as you can see, there is plenty of room for at least one graphics card of almost any length.
