I know I'll be disappointed if it doesn't come with that spec and I did add comments to the side reinforcing the fact I am realistic, but I would expect it to at least support 24GB considering there are Sandy Bridge mainboards that do support that while 1GB graphics is pretty standard now (well for PC).
Do you have any links? The only LGA 1155 boards I've seen that have support for more than 16GB listed are those that are certified for Xeon processors, which can use 8GB ECC unbuffered DIMMs. Though these DIMMs should technically work with the Core i7 processors, with ECC becoming disabled, manufacturers have never put such things on their spec sheets before. I'm curious if manufactures are listing 32GB support in anticipation of non-ecc 8GB DIMMs coming to market.
