The PCs based on Streacom aren’t cheap. I priced a setup at EndPCNoise.com, with the Streacom FC10 Alpha: FC10 Alpha (with its heat distribution), $1369; ASUS Z270-A (1151/Kaby Lake) motherboard, +$30; i7-7700 CPU (Kaby Lake, 3.6 GHz, 65W), +$344; 8GB Kingston DDR4 2133 RAM, included in base price; External Pico PSU (fanless, 150W), included in base price; Ubuntu Linux LTS (x64), -$100 (that’s “minus,” as in reduced from the base price); Samsung 960 EVO M.2 NVMe 500GB SSD for OS, $195; no additional storage (see next paragraph); no optical drive, -$65 (again, that’s “minus”). Total: $1773.
Samsung 850 EVO 1TB SSD, $349.99 at Amazon (versus same for $415 at EndPCNoise.com).
Total: $2122.99. Before tax and shipping.
The above would be a dandy HTPC for Roon. But it’s more than the $2000 of the Roon Nucleus+ (although technical details of the latter, especially the power supply, haven’t been fully announced). And it’s somewhat more than the ASUS GD30CI (which too has an i7-7700, but with 32GB RAM) that I use as my main desktop and that runs pretty quiet (no fan noise so far).
So the Roon Nucleus+ is more attractive than I thought before.
