Is there any way for me to use a computer without a hard drive?

Hey everyone. I ended up with this computer that works perfectly fine but it dosnt have a hard drive in it. So theres really no way for me to use it to my knowledge. Is there any way for me to use it without a hard drive? Ill probley eventually end up getting a hard drive for it but I just wanted to know if its possible to use a computer without one. Also if anyone has a extra sata hard drive lying around id love to receive it for free haha Dosnt matter how many gigabites it is just as long as it can hold a operating system. Thanks everyone and have a awesome night!

Linux live USB drive. If you're at all comfortable with Linux, or you're interested in trying it, it's an option as long as the motherboard supports booting from USB.

You can use an iPXE boot disk (CD or USB, or burn to NIC ROM...) to netboot Linux from the internet.
