This is how Canadians cool their computers! Smart, Cheap and WORKS!
I swear I have both of those computer cases. Both on old machines from ages ago, that are not in use anymore though. My newer PCs use designer aluminum cases because I built those when I was single and had the spare money.
yeah the silver case I have had for about 10 years… its a shitty p4 2.4ghz with 2gigs ram 160gig hdd and 512 video… only for lineage and ts… the black one is a newer case but cheap… not all that good however the hardware inside is NICE 
which explains the 20" fan ahahahaha
