Also, if you just want a small grow and are not dead set on a PC case, I have a link showing where people are consistently growing 1.5-2oz of supposedly very good weed every 9 weeks using a stock AeroGarden and Lowryder 2 x AK47 seeds with no additional lighting, no reflection, and adding nothing but an airstone, better nutes, and a small fan. It's in another forum, so I can't link it but it's a great read with lots of pics if you want me to PM it.
