You could be thinking about Zimmers.net
He is a Commodore collector in general but I know he owns a CDTV CR, CDTV, to many Commodore PET's to be healthy and much more.
Some of the pictures are ones he got from ebay but most are of ones he owns.
Commodore Pet heaven
He has a couple more computers than me
His site is well worth a browse.

Me, I only have a few Amiga's, I dont really collect the extra hardware or much software.
I do have 19 Amiga's, plus a few dead motherboards but thats it at the moment
