5u/6u chassis???

I'm trying to figure out how to condense 3 pcs into a smaller space without compromising cooling and low noise. And also be able to move all 3 of them together or tinker with them if i need to. I will admit i'm not too familiar with server stuff i've always advocated for using tower type chassis when you can to cut down on noise as most SMBs I have worked with aren't really large enough to warrant massive rack setups and can easily get by with a couple cheap atx cases most of the time.



anyway...

I have been looking at 4 pole rack things or whatever they are called 12-15ish u racks are cheap and 4u cases are cheap which i like but they all have ****ty 80/92mm fans for exhaust. I don't see any other major issues as far as fitting regular stuff into a 4u case besides maybe 4u not being tall enough for my go to staple for cpu cooling the hyper 212 evo.



does anyone know of anywhere that sells really cheap 5/6u cases? as i think something slightly taller than 4u with 120mm fans for exhaust would be perfect. I also don't give a **** about hard drives or disc drives. all of my systems currently use just 1-2 ssds and maybe 1 3.5 hard drive. I found a place that sells some but they come with stuff in them for 1000$ or you have to call to set something up which means price hike...



or does anyone know of a 4u case that doesn't really need the 80/92mm fans in the back and just maybe has spots for 120mm fans?
