I actually don’t think $2,000 is needed to build a solid board i built this board useing what I would consider a be very nice and solid board for around $800-$900 using a mix of high and mid tier parts. It did take a few months of planning and i waited for good deals on some of the components I used to come around but at the end it was well worth it.
Also your not alone my first buildhad loads of issues and the board i linked above is the only one I’ve built that I’ve yet to have to open to fix anything.
