Asked a similar q on here a year or so ago but the answer doesn't really fit my needs now, so I'm here again...
Been assigned the task of building a NAS box for my school and after telling them to buy a microserver, they came back to me saying its too expensive at around 250 quid (and via germany) at the moment for a basic 4G model. I looked up the CPU and it seems to be available for 6 quid, so I can see their lack of enthusiasm for such old tech and that price.
So, I'm thinking I can build em a box and started looking around at options. I've found motherboards with 4x sata and an M2 slot for under 40 quid so it seems I can build one relatively cheaply.
Is there anything i need to lookout for on any of the components, I know the microservers use ECC memory, which is apparently better, but I don't understand it enough to know if I should be striving for the same for this project.
