do you think in typical atx case usb 3.x
wiring from the mb to the casing front side connector 30 cm would be too much
to spin up a 2,5 hdd, adding 30 cm cable.
just using a 1m cable from back panel only usb sticks work.
with hdd no change.
For several years I operated this drive attached to the USB 3.2 Gen 1 Connector on the front panel:

Never observed any issues with USB power (5V at 900mA).
You don’t say what kind of drive and enclosure it is.
I bought several used laptop drives for $6-$10 each, WD, Seagate, Toshiba etc. I used them in a $6 Orico clear plastic 2.5 HDD enclosure. I copied 100-300 GB’s of data from them to the desktop daily, something like 14TB’s total and never had a problem.
I have some nice Aluminum 2.5" HDD enclosures and apparently they supplied cheap cables with them. I had problems when I used the supplied cables but they worked great with a better quality cable.
So make sure you have good quality cables and you should be ok. Some drives require a little more power than others too, so I try to get drives that require a little less power.
I also a have an external 2.5" Toshiba brand 1TB drive that came in a factory enclosure and it works just fine too. It’s 10 years old with very low hours and works just fine on multiple laptops and desktops. It’s a Toshiba Canvio Basics 1TB USB 3.0 External Hard Drive (HDTB310XK3AA).
I do have problems with some USB-C 10 Gbps NVMe enclosures. It’s actually the NVMe drives that require more power that are the problem, some work fine. I’m going to get a powered USB-C/A 10 Gbps hub to solve that problem. That’s an option for you too if your motherboard isn’t supplying enough USB power.
