Maybe I should add the one I just finished to this thread, I’m pretty close to the same price because I was able to recycle some things. Using the n18 board I bought from you.
Mine definitely would have been easier if I bought a new case! (but I got 6 drives in the array) What I have for my build is on Serve the Home forums in their DIY section, same user name.
No performance data from mine yet, just finished the build this morning and I still need to create shares and move VMs to this new server. And I really want to add SSD to mine, but not spending the extra $250+ to get there just yet. Mine only needs to be 3-4TB useable for my lab.
