It's only about 60% of what you're asking for but I'm a fan of DKOldies: https://www.dkoldies.com

They're a US storefront but they ship internationally. They do a great job restoring consoles. And they have amazing customer service (one of the SNES Controller refurbs was a no-go and they cross-shipped a replacement with no expectation that I even returned the defective one).

I don't know if they have old computer stuff, mostly just consoles. They have Atari consoles sometimes though.
