Am doing my own research and what I'm lookinf for is a DLNA NAS box, needs ot have an RJ45 plug, so not a USB one that comes with DLNA software. No adverse to it having a usb port though to attach additional storage but that would be a luxury but would consider paying more.
Size wize, physically can be anything, I'd like it to be quiet though - and be at least 1TB with either removable drive to upgrade it as and when, or a USB port to attach external; extra storage. Doesn't need things like SD card slots etc but again wouldn't discount it if it did. Doesn't need vuideo out ports this is purely going to stream over the network via DLNA to my TVand XBOX.
Budget: £110 plus or minus £20.
Many thanks, Will post if i find more stuff as well.
