Some do seem to hate iMon, but I have been using it in my silverstone LC20 case for 6 years and it works perfectly for me. The original remote is a bit of a monster - loads of very small keys - but I use a harmony remote and with this the shear number of buttons on the remote turn into an advantage - loads of buttons that can be used for programmable LCD functions.
Although the driver is old (I guess three hardware is simple and doesn't change) the Windows iMon Manager tool is regularly updated and I have found it to be functionally very capable. Not as complex as EventGhost or Girder but generally very up to the job.
I have just gutted the LC20 to install a new Ivy Bridge MB and SSD. The iMon carries on doing its job with any hint of response lag eliminated.
