New computer for 10yr old Ethan

Hey, I started this fund for a new PC build for me and my son a while ago. It has not turned out good, we purchased all the parts solo but need to get a cpu and motherboard next. Looking for donations to help out. Wife won't let me spend much more on parts but without a cpu and motherboard I've wasted a ton of cash on other parts. If anyone could throw a few bucks my way to help out that would be great. Thanks.
