Hmmm by doing that then the computer hardware will be almost empty.
Not really, GPUs and actual computer hardware topics are still there, and will be there.
I guess that board was actually created for ASICs (correct me if im wrong though)
I don't think so, when that board was created there was little to no ASICs, if you scroll back a few years, you will see that most people were selling their PCs, Laptops, and related parts, recently since mining bitcoin (as well as many other coins) is only done on ASIC miners, that board became dominated by ASIC topics.
The thing is, ASIC miners only interest people who mine with ASICs, those are unique and specific users, the rest of the members who visit that board do it to shop for a laptop, headphones, a new ram stick, or anything computer-related, and on the other side, someone who wants to buy/sell an ASIC miner will have to filter those users selling their PC parts, it's just a mess because the audiences of both categories are different.
