These boxes are loud, that's the main issue. They all have notebook-type blowing fans that whirls all day long. Second, Intel's branded hardware is known to be overpriced, they cost twice as much as noname-branded Chinese fanless boxes with exact same internals. They all come barebone, so you'll have to buy SSD, HDD, memory and wireless card.
If you need a portable PC, you're better off going for similarly-specced laptop, if it's desktop aesthetics, look into MiniITX, if HTPC or NAS, just go for Goldmont motherboards, you don't need an i5 to play animes.
As for liberty: besides proprietary UEFI implementations, non-free microcode and firmware for CPU to boot, latest generation Intel GPUs also need non-free firmware to function properly. Yes, they will run Trisquel or whatever antelope-approved snowflake distribution of Linux kernel and stallmanite parasite attached to it in headless mode, don't even expect the best GPU performance with libre driver. But if you treat the proprietary firmware (that never gets executed on main system memory or processor cores) as part of the hardware, you'll be able to escape mental loophole of freetardism pushing the Overton's window even further perhaps.
