I could use the ssd for cache mem in a qnap or synology. I dunno, i basicly wanted to use the thinkcenter as a mb for hdd. Say an upgraded version of a nas which have way less mem capability or cpu. But after watching those vids maybe best to go for something new and not refurbished. Now in”just” have to choose what for what price. I was originaly gonna buy a dell san or something refurbished but thats going to a whole other level and cost way more time.

Can use the ssd, memory and maybe the processor

Ah cool. I will check this out. Its been a long time since i build my own pc. But i guess the basics stay the same. Can always strip one of the lenovos

I will look into that. Doesnt have to be linux but seems most versatile.

Yeah the usb is indeed not the fastest. The lenovo mini pcs i already have (got 3 different kinds) and want to make them servers just havent gotten around to it. Thing is if i build a pc just for the nas thats going to cost me about the same as buying a synology or other nas. But yeah usb not ideal.
