Old external Western Digital 1tb 2.0

Hi everybody. O don’t know if this the topic. I’m sorry i am new here. Well i have this big fella (Western Digital WDBAAU0010HBK-00) and today the power/usb board literally died . I test da charger and is died too, but the HDD are safe, I have tested too. my question is, where I can buy a new one board for this old fella? I know I can buy a new case from the brand or another Brand and is not expansive but I like the old one, if I can, I like persevere this old guy.

Thanks
