Hello, it looks like server cabinet that I just got off of Facebook marketplace doesn't seem to have rails or a rack. I'm not sure what the terminology for all of this is but I don't see a clear way to mount anything to the server cabinet could any of you kind souls explain what I need to buy for this cabinet?
A - you need to make sure that the opposite side can be removed, or has sufficient venting. Rack equipment moves air front to back (cold aisle to hot aisle) If all you have for venting is the top then youre going to need some heavy duty fans to lift the hot air out of the cabinet and exhaust it somewhere
B - You can buy rack rails - theyre basically angle iron, and either tapped 10-32, 12-24, M6. AV racks typically use tapped rails. Server racks more commonly use square holes that accept cage nuts with M6 screws. Assuming you have 72" internal clearance in height, then https://www.server-rack-online.com/7205-es2p.html or https://www.penn-elcom.com/us/42u-rack-strip-with-square-holes-1-16in-thick-r0863-2mm-42 rail kit is what youd want (the first link is for a pair, vs the second link is per rail). Dont forget the cage nuts and screws https://www.server-rack-online.com/hdw-105-50.html
For 19" racks, the distance between hole centers on the rails needs to be 18 & 5/16 inches. If you dont have about 20 inches between the cabinet walls (assuming about another 1.5 inches taken up by the width of the rails) then this cabinet is probably a bit of a lost cause
All that said, for the $100 you'd spend on rails, theres probably someone out there with a proper server rack trying to get rid of it for that or less
