My "new" computer is a laptop with an 8th-gen i5 and 8 gb ram salvaged from the Windows 11-incompatibility heap (actually 3 of them, so I have 16gb in it). I installed Kubuntu on it and it runs extremely well. I can even install Windows 11 in a VM if I really need it. I'll probably be buying new (old) ram for it and maybe a bigger drive.
