Yeah those were the same ones I'de been looking at except I was going to buy the 32" wide one. So far I've only spent around 45 dollars on the wood for the frame, but I haven't finished purchasing everything for the build, I've been busy with final exams. I will be getting the rest of the materials this weekend, and based on what I've looked around at online, it should be about 60-80 dollars in total? I'll be happy to let you know once it's done.
Those seem like solid cases though, good choice.
