Are there companies out there that buy new stock Macs and perform certain upgrades to them then sell them? I found one company that sells custom built MacPros. I think that specific mac is called Silverado Mac Pro: http://silverado.cc/shop/product.php?productid=1081&cat=0&page=2 Anywho, I was just wondering if there are other business out there that kind of do the same thing but for other mac products? If you know of any, can you please link to them. Thanks!
