Xoxide has been a source of PC modding equipment for years. It is sad to see them go. They do have an “everything must go” sale going on.
Check out the goodbye message and look for some bargains.

According to this post in their forums, Xoxide has been sold. The site is back to looking like it was pre-sale. Some folks are worried about if / when they will get what they bought under the sale. See:
