I have a Moneual 320 with the display, i have an A6-3500 in there and it plays everything fine.
I have a few remotes including a logitech harmony (I don't think the original infra red thing works with non proprietry remotes but I bought a media centre remote with dongle) but I find i never use it and use my tablet to control it, the XBMC app lets me start it up and shut it down over my network and it boots in to XBMC then I use that or Yatse to control. If I need to do anything else on it I have Remotedroid installed on my tablet.
