as above I'm selling my Readynas Duo. This is a special one as it's had an extra large silent fan fitted to it so it runs at around 916rpm and is as near as silent as i think you'll get without using an SSD and / or a heatsink the size of a fridge.
No HDDs are included as I need those - this has run flawlessly with 2 x 2TB drives in it and has always been available on the network and served media via DLNA whenever I needed it to.
Memory upgraded to 1Gb, verified compatible Kensington branded RAM.
I'm after £50 collected from Sheff, or posted for the extra cost of RMSD
