the cases i was able to get relatively cheap and my cheap i mean free, from a recycler, i have all the parts to assemble about 30 more i think, but i dont have enough back and front plates, just tops and sides.
The Modded Gridseeds also were gifted to me so ultimately i dont have anything as far as money into it just time, laying the case out, and bolting the greed seeds to the base so they dont shift.
and ive though about selling a case with the layout i currently have in the photo set up, just didnt think anyone would ever be interested, because like he said gridseeds will be out dated soon
