I've been doing this build since early last year, posted it on Battlenet forums a while back. I continue to have really good success with the build into Masters. Composition is MARINE/THOR/RAVEN/BANSHEE. Please leave constructive feedback, as I'm always looking for ways to improve! If you have any questions please ask. Cheers!
12 Rax 1st
14 Refinery (3) - halfway through rax build

MOVE TO NATURAL
Start moving OC
Bring 4 workers + army out
2 x Refinery (3) and 1/2 Bunker at natural main
Bring 6 more scv's from main to natural
Load Bunker with marines
2 x Starport + Tech Lab
Tech Lab on 1 Rax
Research Combat Shield
(In that priority sequence)
Bring out near max army @ 13-14 minutes to closest xelnaga. Establish..
3rd Base, extra Rax, and Factory/Starport as economy allows.
Hotkey Banshees (cloak, position etc). Hotkey Raven (for PDD). Cloak banshee's and hit his main base probe line, then bring them back to main force and hittem hard. Bring 8 or so scv's to repair, position army according to enemy composition. MAKE SURE TO LAY DOWN PDD's and to target fire Colloss with Banshee's. Do not bunch up and try and keep your Banshee's to the side rear of opponents army.
Zealot heavy - Together
Stalker heavy - Together
Colossus heavy - Thors front, Marines behind, Banshee taking out Collosus
Immortal heavy - Marines/Banshee front, Thors behind
HT heavy - Thors front center, Marines side Banshee spread and to side and/or over the opposing army.
Note: If he is doing harass with Phoenix you can expect some air-units, cut some banshee's for vikings (I often add a CR on one of the Starports instead of TL) You can also do this if you know he is Colossus heavy.
Important: The build is a little weak early on. Stash the scouting SCV behind his natural and check regularly to determine if he is FE'ing or putting on early pressure. If he is putting on early pressure, lay down a second barracks. Always make sure you have a minimum of 6 workers on hotkey (auto-repair mode) in order to quickly repair Bunker/Thor. Don't be afraid to bring more SCV's under heavy pressure.Wait until you have 2/3 Thors and more marines before pushing out into your natural
