thanks for the offer, a little soon for try-outs am very much in the considering in which direction to swing.
Current situ is an old 21.5 iMac (so no vesa), plus second monitor - used mostly for work. I'd like to get the monitor (plus another if replacing imac) off the desk and on arm mounts, so SFF/Mac mini are where I'm leaning. 2 x of us both 'work' on OSX and why there is no real reason why we couldn't switch to Windows, there is a lot of inertia the other way.
aside from that I want to play games!
