Decommissioned my ancient (it's a single-core atom!) and starting-to-crash-a-lot HTPC/home server yesterday.
Currently trying to remember what else that box did in addition to being a HTPC. I'm sure I've forgotten to install something important...
Anyway, replaced it with a Vero 2, from the guy who did OSMC, a Debian-based distro optimised for use with Kodi media centre software. It's a tiny dual-core ARM system with a nice meaty gpu and a very neat radio remote - so no line of sight needed; plenty of USB ports; low power consumption (10W max) and best of all for future proofing, hardware accelerated playback of h265 video. For a tiny box it's impressively powerful - I was playing 60fps/1080/h265 video earlier and it didn't miss a beat. Might struggle with 4K but I'll need a new TV and some higher resolution eyes before that's a problem.
It's also cheap, which is a plus. Not quite so cheap as buying a Raspberry Pi and all the gubbins that goes with that, but it's cheap enough to make the time saved by not dicking about worth it. Take the Vero out of the box, plug various bits (usb disk, ethernet, hdmi, power) in, done.
Oh, and it'll play back 10bit h264 so the fucking idiot anime scene groups who insist on using that can finally fuck off, although I bet they've all started using 16bit h265 or something equally pointless now anyway. Wankers.
