The chest contains a full set of Orcish and Glass Armor with Shield and also (every) weapon of both types and 50 arrows of both types. 20 Iron Ingots just as a starting point so you can make a few daggers or just keep them, the materials to craft 2 backpacks (one for self and one for a follower) or just keep the stuff (there is also an anvil next to the chest if you care to use it).It also contains 10 of each ingredient that the Khajit caravans sell so having that free content installed and enabled will be necessary. I also made all those ingredients except the Minotaur Horns and the Ogre Teeth weigh nothing, the horns and teeth weigh 0.5 and 0.2 with this mod installed.

It also contains some useful enchanted items for disenchanting > A soul trap, a fire, and an ice enchanted dagger. Necklaces with sneak, stamina regen, waterbreathing, disease immunity, lockpicking, and magic resistance. And Glass Boots of Muffling.
And lastly it also contains the Dwarven Black Bow of Fate and 5000 gold.

I've added some Hearthfire adjustments to this, you can buy 75 Sawn Logs at a time for 750 gold now so buying Logs isn't so tedious (I couldn't get the dialogue updated, kept causing my CK to freeze but it does work). And I modified the contents of the crafting chests at the 3 houses you build to contain more items, at least a few of everything you need... Goat Horns, Straw, Glass, more Iron, Clay, and Stone. It's not entirely the full amount but it's close and in the chest at each house. The quantity of Iron Ingots is 60.

This mod may have incompatibilities with any mod that also modifies the same Rare Curious ingredients, in any case just put the mod that you want to win those conflicts lower in your load order.

It will also have incompatibilities with anything that modifies those BYOH chests, solution would be the same.  However if you have any other mod that modifies the scripting to the buying lumber quest you will have to grab the files BYOH_TIF__0100696B.pex and BYOH_TIF__01003002.pex from the scripts folder of the one you want to win the conflict and overwrite when pasting it into that folder.  By default those files would be from the LAST of the mods that you downloaded if you overwrote, if you chose not to cause you are already aware of such then you are fine.  You'll find this by going to your data folder then your script folder is the target.  After that you'll have to repeat by going to the source folder (inside the data folder) and then the target folder is that scripts folder and the files are BYOH_TIF__0100696B.psc and BYOH_TIF__01003002.psc.  After that the conflict is solved and the winner is the one you chose.
