I'm in the same boat as you, minus the already subbed. I've been looking around for cheap mini PCs that I couod slap to the back of a TV/monitor. I've been scouring the threads about what the minimum standards are CPU/RAM wise so I don't buy a cheap pc that's too cheap. The ghost won't be out for another 3 weeks, and since you've already subbed, wasting that time/money ain't the best strat.
My findings are something like this:
Or for $120
It has the gigabit ethernet port. It has dual band wifi. Enough ram to handle basic shit. Enough power to output 4k comfortably. 2 or 3 USB 2.0 ports, a 3.0 port, VGA, HDMI, microSD and, what made me pick this one over the other ones like it, support for a 2.5" drive caddy. That plus a $30 180GB SSD, makes it a perfect TV box.
This is essentially what I'm going to do. I'm also going to look at touch screen portable monitors (170 for a 15 inch), powerbank with AC outlet (100 bucks) and a mobile wifi Hotspot (60 bucks). That would give me a 15 inch tablet (albeit clunky af) with the power of a $2000 gaming rig literally anywhere for around 600 bucks.
