I think for normal gaming + movie watching OLED burn-in won't be an issue for PC use, even with the taskbar present you would need to go to extremes to get burn-in. Monitor on 24/7 with no sleep modes, max brightness, etc. Rtings has a good read up and video on what they've seen on OLED tv's...
The one I'm looking forward to that's very promising is the new LG 27GL850. Should be out by end of August and hopefully some reviews shortly afterward.

Same for me and I've been looking for a case to do just that! The photography cases I've looked for are just too large though, what are you using as a case?
