Advice on moving from ESXi where to install

I appreciate any help as I am trying to move from ESXi to Proxmox but i am confused on the install.
I am learning in a home lab and picked up an old Dell server (R520). I am new to ESXi/Proxmox/servers etc

I have 6x 4tb Drives in the server. ESXi is running on a USB thumb drive. The 4tb drives are set up as RAID5 in ESXi.

If I want to move over to Proxmox is it OK to install it on a USB thumb drive and have my server boot from that just like I currently am with ESXi?
I have not read anywhere in the docs that this is OK so I am assuming at this point I must install it on actual drive.

I am guessing if that is the case then I am either going to have to pull one of the 4tb drives and replace with a small SSD or something as there is no point using 4tb to install only Proxmox on.
I did the same thing a few weeks ago. I run my Proxmox installation on a ZFS mirror (SSD). Can be small, like 120 GB. If you want to "save space" I recommend getting USB-to-SATA to be able to use real disks, but through USB. Don't know if it's recommended, but it worked for the past 5 years on my TrueNAS server (which now is replaced by Proxmox).
