I reused the same beige Chieftec/Antec 1200 cases (I think that's the model number) full tower with the four 80mm fans that sit in those ugly, plastic purple carriers for about 10 years/5 builds. Then I bought a $300 Lian Li, which rattled like crap and dented if I looked at it the wrong way, so i sold it. Then I bought an Antec P180 (awesome case) and had about 4 builds in it. Then I decided to go whole hog. I bought a 30U, 30" deep rack and two 4U rackmount cases/rails. I replaced the fans in both cases with desktop-grade fans vs. the jet engines they came with. My two systems are quieter than most PCs. The noisiest thing is the 5 traditional hard drives in my NAS. One case holds my NAS which has only changed once in 6 years. The other holds my main PC and I've had about 5 builds in there. It's bigger inside than a full tower, I can just slide it out and remove/replace whatever I need to and slide it back in. No more cut hands, no more broken fingers from trying to snake wires every which way. The rack is right next to my desk. Sure, the rack takes up a lot of room but I have my printer on top, a big UPS that sits on the bottom, out of sight, and an 8-port Gigabit switch mounted on the back with a single connection to my router. I do miss the excitement of buying a new case but the ease of maintenance and assembly makes up for it. This thread is timely as I just emptied out a storage unit I had and found a 5U pedestal case (YeonYoung W201 I think) that is rack mountable. It has a nice, quiet 120mm intake and exhaust fans. Cha-ching! I'm transferring my main PC into that this weekend. Should be even quieter than the two 80mm fans in my main PC/rack case I'm currently using and as a bonus, the Hyper 212 cooler I've not been able to fit in the 4U will fit in this baby! I'm stoked. This is the 5U case And for the heck of it, the product page. http://www.yycase.com/yy-w2xx.htm I got the version with the feet but they screw right off as do the top/bottom panels which exposes the mounting holes for the rails. The case came with an 80mm fan mounted in front of the drive cage (pictured below) but that was an easy mod to a quiet, 120mm fan. ps All my rackmount cases have removable front filters and I tape off any side/top ventilation holes that all rackmount cases have in order to ensure proper front to back airflow with the lower-speed fans I use. It was a lot of research and work, but worth it to me.
