Simply. Not. Possible.
Sorry, and I mean no offense, but a 108 in any attribute requires (a) more than 25thlevel, (b) epic level spells, and/or (c) far more than what you've listed here, in the way of obscure attribute boosters and enhancers.
You've got a few things wrong yourself. First off, the benefits from Bear Warrior *replaces* the benefits form Rage or Frenzy (IMO, the BW's choice). Thus, the +4 from Barbarian(1) is no longer in effect. Further, an ECL 25 Half-dragon Minotaur has a Level Adjustment of +6, so this character has 19 hit dice. Thus, while the +4 from level is a correct total, those modifiers are for 4th, 8th, 12th, and 16thlevels - not 8th to 20th as you state (sorry to nitpick, but it means the character is only ONE level/HD form another attribute increase). ^_^ Sadly, the Belt of Giant strength is useless - the Bear Warrior benefit is an enhancement bonus, and so is the Belt ... thus, they don't stack.
So, based on that, I get [ 18/base +4/level +5/inherent +16/enhancement +6/frenzy +4/morphic +2/size +8/half-drgaon +8/minotaur = ] 71 in total. Which leaves no less than thirty-eight points unaccounted for.
As for Constitution, I also note similar errors in Sledge's accounting (mainly bonus-stacking issues); I come up with a 47 total (the belt and bear warrior enhancements don't stack, and the bear warrior benefits still *replace*, not stack with, those of Rage).
Look this then:
