Every homelab build I see uses those cheap 1U sliding shelves that sag after 6 months

I put a $40 rack shelf under a 35lb UPS and it bent like a taco inside a year, so why does everyone keep buying these instead of spending $15 more on a solid steel one from a server pull?

Honestly the heat is the part nobody talks about. I put a normal sliding shelf under a switch in a closed rack and within 8 months the rails started binding because the metal expanded unevenly from the heat cycling. Those cheap ones are stamped with no relief cuts or expansion gaps. The old Compaq shelves I pulled from a datacenter have these little slots cut into the sides that let the steel breathe without warping. If your rack runs over 85 degrees that $25 savings is just buying you a future headache.

Heard serverpull guy say those HP trays handle way more weight than rated.

Yeah those cheap shelves have like 1mm steel if you're lucky. I grab the old Dell or HP rack shelves off eBay for $25-30. They're rated for like 100lbs and don't budge. Check the listing for "tray" or "sliding shelf" and look for the thick stamped steel ones with the rolled edges.
