I know everyone has their own opinions of them but I'm a fan for what they are. Right now I have 3 of them that I've gathered over the years (one with ESXi hosting my firewall, one with TrueNas for backups, and one with ProxMox for a few LXCs).
Overall, they are great little boxes, I had three of them in my living room for years when I was renting and they were pretty much completely silent after boot. The dual core celeron that comes with it works, but can be upgraded to a Xeon e3-1265l v2 (quad core + HT) for $25-50. RAM I think maxes at 16GB, but if you want a box to run a dozen light services or so, its not a bad box (insanely quiet and pretty power efficient).
I'd like to see how a dry heat compares because I've always heard it was better. This past week where I'm at in the states has been terrible, triple digit heat (I think it was 102 on Wednesday) with super high humidity and ridiculous UV levels; the air is thick and like a blanket wrapped around your head the moment you walk outside. Nights have been upper 70's-low 80's, I know it could be worse (thank god for a pool and AC), but this is way hotter than when I grew up.
