Recomendation for low effort SATA enclosure that can do direct connection of drives to HBA

I haven't found any that include power supplies and basically what I have found are cases or sas/sata drive cariers that you need to build up a whole PC from parts not excluding having to get a PSU.

Is there a turn-key product here?

Alternatively I've been thinking of modding one of these USB storage boxes because it is already a nice case, no wasted space for a motherboard/CPU and includes as PSU.

A recommendation would be prefered, but if anyone has also modded any of these USB enclosures, how did it turn out?

The value on these boxes is good as it comes with a nice case and power supply. However USB is slow. Is it possible/has anyone done it/ to just power the drives and link up each drive to an sas/sata HBA on another computer?

I'm imaginging something like one of these to mod...
