Has anybody actually looked at the size of that behemoth? Mainstream or not, who would put that unsightly beast on, in, or next to their desk?
The water cooling feature is WAY over the top and adds complexity that is IMO not mainstream.
Mainstream to me means not only parts that someone may use, but also the finished product that one ends up with. Aesthetics play a huge role when people are spending any amount of money and that should probably be considered as well. Again, just my opinion, but I think the average or "mainstream" user would not want anything to do with the machine built this time around.
And since I am putting in my $.02, here is my take:
G33/35 or G45 Micro ATX board
Silverstone Micro ATX case
1 x LG Blu-Ray optical
1 x 320 GB Raptor
2 x 2gb DDR2-800/1066
1 x 600w Zalman PSU
1 x Q9300
1 x Sapphire 4870 (1GB toxic version)
1 x 3.5" card reader
1 x Silverstone CPU cooler
2 x ANTEC tri-flow 12cm fans
The above should come in around $1,200 to $1,300 from Newegg.com and would be fast, quiet, good looking and quite fast at 1680x1050 up to 1920x1200.
