@sabi Tho depending on your budget, time and skills it may be Worth the effort for you to look at the #Wee86, #WeeCe, #86duino and other projects and see if something like a #SOM / #SBC module with #ISA + custom #PCB may even be a better option, as there are #Vortex86 Chips down to #i8086+#i8087 and those will sip even less power than the #NuXT, making it way more fitting for a short 19" 1U enclosure if you want it to be basically #fanless and #silent to tue point of only having the PC-Speaker as source of noise...

But IDK if you're good at PCB design or what your skillset is in detail or if you just want one for yourself or something you can market to others as a side biz...
