Yes, Though it was not very hard, Since I took this picture it is now upto 12 hard drives (11x1.5 TB + 750 GB), I setup a mini radio station that broad cast on 87.50 fm, with remote control for android phone (XBMC) so i can select what music(and video) is playing, I now have all my torrents running off this box, and it has all my classic games on it (NES, SNES, N64, + others), I have removed the AMD II 6000+ processor, and placed a semprom in it instead clocked at 2.2 GHz, my current power consumption is at 180 watts active, 95 watts with the drives spun down. The only real disadvantage I have with this over my unRAID setup is the fact that I cant mix drives anymore. Which is not really a problem since I sold off most of my smaller 250-500 GB HD, and I took all my 1 TB and setup a array on my person PC.
And for anyone wondering it takes 22 hours for me to grow my array when adding a disk, and I can still use my network storage during that time, rebuilding (due to lost disk) I do not know yet.
With the new 3 TB disk being under $150 on sale its just a matter of time until I upgrade again.
