You should probably build it yourself. You won't find many prebuilts that fit your needs.
I would but my friend is a pain in the rear end. I'm on a short string here, he's so far stuck to the agreement HOWEVER he's made promises before then just said "Nope". He wants me to find a used one, cause its cheaper. He's lazy so I doubt he'd order parts.
