It all started because I lived in an open-concept apartment and refused to give up on an HTPC in the living room and bedroom. I think I ended up with the cheapest way out. It was actually about not giving up as living on a second floor apt with people above and below really cramps your wire-running options. Baseboards don't extend all the way and there was a flush hardwood to tile transition (no thresh-hold from living room to kitchen) prior to the carpeted bedroom.
I'm not as experienced as a builder/carpenter/trim carpenter, but in my lifetime thus far I've demoed a house down to the exterior walls/studs/ceilings with my sister, brother in law, uncle, and dad. Ripped out walls, carpet, tile, linoleum, roofing, etc. Replaced rotted sub-floor, hung sheetrock, replaced exterior door, repaired roofing, rolled felt and nailed shingles, painted interior/exterior, etc, etc, etc. Pretty much everything in renovation, never a grass-roots build though. Never solo (except ripping/scraping linoleum kitchen floor and replacing with tile). Sometimes handiness can't get it done
