HQ:
~Daemon Prince
-Wings
-MoT
-Warptime
-Wind of Chaos
Total: 185
This is alright, a bit points costly, you could consider having only warptime, either way it works though.
~Chaos Lord
-Terminator Armor
-Combi-weapon
-Daemon Weapon
Total: 150
A Daemon prince would be more competitive, but this is a fine build if you really want a termie lord, although you probably want him with a landraider.
Elites:
~Chosen (7)
-Meltagun x2
-Champion
-Power Fist
-Plasma Pistol
-Meltabombs
Total: 201
You should really drop the plasma pistol and melta bombs and buy 3 more melta guns. These guys are good at backfield armor killing (I take it the rhino is going with these guys? It should be)
~Terminators (5)
-Chainfist x3
-Reaper Autocannon
-Lightning Claws
-Combi-weapons x3
Total: 230
I dont think the reaper autocannon is worth the points, but its up to you, otherwise these guys are fine (I take it they are tank hunting? with the termie lord?
~Dreadnought
-Missile Launcher
-Heavy Flamer
Total: 105
If you're going to run a dread, you are really going to need to do it with two CC weapons, otherwise you risk it shooting your guys quite a bit.
Troops:
~Berzerkers (12)
-Skull Champion
-Power Fist
Total: 292
These NEED a rhino. Reduce the squad to ten (or 8, khorne's number) and buy them a rhino possibly with extra armor.
~Chaos Space Marines (10)
-Meltagun x2
-Champion
-Power Weapon
-Plasma Pistol
-Meltabombs
Total: 220
These also should have a rhino. And plague marines would do their job better. Same build, but just PMs insead of basic marines. Also, the plasma pistol and melta bombs aren't necessary.
~Chaos Space Marines (10)
-Meltagun x2
-Champion
-Power Fist
-Meltabombs
Total: 215
Same as above
Rhino
-Dozer Blade
Total: 40
Fast Attack:
~Chaos Bikers (4)
-Meltagun x2
Total: 152
Bikers w/ MoN are beast. You could try that out.
Heavy Support:
~Obliterators (3)
Total: 225
Brutal...
~Havocs (5)
-Missile Launcher x2
Total:115
~Havocs (5)
-Missile Launcher x2
Total:115
Havocs should have as many heaby weapons as possible (4 missle launchers is always good). Also, heavy support redundancy is always good as well, more tactical flexibility, so you could consider making these into havocs.
~Predator
-Lascannon Sponsons
-Daemonic Possession
-Dirge Caster
Total: 130
You should really drop the daemonic possession, the BS reduction isn't good for a las predator.
You have too much heavy support, combine the havoc squads into one and you'll be alright.
Grand Total: 2375
