Before you yell at me for how bad gpu mining is, its the only thing within my budget right now. But Im not sure what equipment to use, or how to set it up. I know I need to set up my mother board and power supply below the GPU rack up top, but how can I fit as many GPUs as possible? I was thinking of using a riser board with multiple slots, but Im not sure if that would work. Anybody mind helping me out here?

GPU mining in Bitcoin is simply not recommended nor is it at all profitable. This is the same for all other SHA256d coins due to re-purposing of Bitcoin hardware (which share the same algorithm).
Your electricity cost will be far greater than any rewards unless you are using an ASIC (Application specific integrated circuit) miner, any even in that case you may require cheap electricity in order to make it profitable.
However, GPU mining does exist in other Proof-of-Work coins that have not (yet) been primarily flooded with ASIC hardware. Ethereum, for example, has a relatively fair enough difficulty to make GPU mining viable in specific cases. I recommend using this site to compare graphics card profitability in different coins.
