System mainly built for gaming, virtualization testing/training as well as coding. It has worked amazing, not a single issue since getting everything installed and overclocked; she has performed above and beyond what I was expecting! Only thing to be hesitant about is when using the Phantek with the R4E motherboard, you'll need to wrap the wire brackets (that hold the fans) with electrical tape as they touch the backside of any card you put in PCI-e slot 1; raw wire + backside of PCB = bad.
The Apple Cinema Display is amazing, though I am still leaning towards the U3013 when its released as the glare off the glass can be... problematic. I don't game competitively so it being locked in at 60hz doesn't bother me thought I have tried researching if anyone has overclocked the screen (they haven't if you were wondering). This thing certainly won't win any performance contests on paper but for what I play - Mass Effect, Crysis, Planet Side, Deus Ex, etc. - I think it is a very solid, well-rounded monitor. Like I said above, I'm not competative, but if you consider yourself so, I would probably steer away. I've never played/used a 120Hz monitor so I can't compare the two, but coming from TN monitors, I really enjoy this thing.
