You see, that video is on a case with a great design, with me building with a budget, I had to go for whatever didn't look terrible and would fit everything (Quite obviously not the best way to pick a case, but it's my first real build for myself and i had no idea what cases were better) so i'm stuck with only a few fan slots, otherwise i would have just watched this and decided how many fans i would need and where to place them.

I have a Thermaltake Commander MS/I Snow Edition (White/Black) ATX Mid Tower Case and I would like to know where I should put fans in it, Inside it is a microATX mobo, a GTX 950 SC and a non-modular power supply. On the mobo it has 2 connectors (Not including CPU FAN connector), one 3 pin connector which is being used by the fan that came with the case; and one 4 pin connector which is currently empty. I used to have an Arctic F12 3 pin case fan plugged into the 4 pin, but this got too annoying so I removed it, I'd like to know where the best fan placement inside this case would be to get airflow on the cpu and gpu but without spending more than probably 50 USD. On a side note, I would like to also get a fairly cheap but decent cpu heatsink, if possible without sacrificing cooling performance I'd like it to have a fitting mechanism without screws but if this isn't possible then screws would be fine. CPU Socket is LGA1150. Thanks!
