PC-wise, I've only built about a dozen systems where I selected the components, and upgraded RAM in a few laptops, but...
● Asus motherboards have always worked for me.
● Kingston RAM has never let me down, although I used Corsair for the latest office PCs.
● WD HDDs have seen better longevity than other makes.
● Samsung SSDs work well.
● I use be quiet! and Seasonic PSUs.
● Stock CPU coolers have been fine for what the computers are used for. The only one to wear out was in this PC, and I replaced it with a Noctua and (eventually) replaced its fans with Noctua PWM ones.
● For cases, I just choose something that looks OK, is in aboout the £80 price range, and gets reasonable reviews - the manufacturer isn't important there, and it isn't really an electronic component. Replacement/additional fans tend to be Noctua.
Other electronic goods I have where I actually had a preference (usually influenced by reviews) for the brand are:
● Hakko soldering station (got fed up with the cheap Antec soldering irons, my fault - they are made well but I should have gone for temperature-controlled in the first place).
● A Sony LCD TV (which needs replacing after ten years).
● A Philips electric toothbrush which seems not to know it only had a two-year warranty.
● Replacement capacitors? Japanese: Rubycon, Panasonic, Nichicon.
● Vacuum cleaner: Sebo - I expect it to last forever.
