Be gentle on Hamish, just bought recently very similar hardware, 5 boxes in all, a few with -i7 8 cpu procc, ex government desk top/tower. Retrofitted solid state hard drives ( big improvement ) bumped the mem to 16g on a few, kept one as w10, for ipad repairs mostly, rest i went Ubuntu ( used to teach Linux server build and maintain ) responds on the internet as fast as i can type. Mozilla my preferred clients on Linux platform, used Dell hardware at about $100 a box, old flat screen TV as monitors ( older Dell retained SVGA/XGA 15 pin and Display Port options HDMI if you must ). Bargains out there, Hamish knows, grin j
