1.Rackchoice 1U Compact Server/Desktop Mini-ITX Chassis - 9.84" Depth,Supports Mini-ITX Motherboard, Business IT Use, Black

It's not super-sturdy but it's "strong enough."

It's basically all stamped sheetmetal, but at least it's solid. Also everything rackmount is overpriced and this was the cheapest shallow depth case I could find.Points added for the included rack screw converter plates, but deducted because the included blank card cover is silver instead of black (when the rest of the outside is black, not that anyone really sees the back but that's not the point.) Also the cover for the back panel (if no motherboard is installed) is amazingly flimsy, and there is none included for if no power supply is installed (which seems like less of a use case though so that's understandable.) Front ports aren't USB-3 (or USB-C at this point) either.Would buy again for the one specific application that I need it for, but not if the price went up.

Too narrow for a standard mini-ITX motherboard. Card slot is in wrong place for Mini-ITX motherboard with a standard 90 degree adapter. Too narrow for even the lowest profile CPU cooler. You should expect having to modify the case and buy and return several parts before you find something that works. I wish I had bought a 2U, this thing has been a nightmare.

the small form is nice, the case feels solid and comes with a fair bit of hardware. i would replace the fans with something quieter. the placement of the fans isnt exactly great. on the mini itx board i installed the main connection is right where the fans are blocking air flow front to rear. if the connector was in a different spot my ram would be blocking it, so not the best place for the fans, i was able to mount a 3.5 inch drive no problem.

it is a cheap chassis with very good quality, with build in 2x4cm cooling fan , but little noise, I am happy to got a good rackmount chassis, the front panel and ear are aluminum,which are smooth beautiful,easy to install my mother board, and the 1U flex Power supply,HDD.
