Mine is 2 years old this December. There's a store where I live where you can pick each part individually so that is what I did (includes full warranty even if the they don't assemble it properly) so it doesn't technically belong to any of the companies above
I have my main rig which is a: Mac Pro 2010 (I think, I will have to look... might be older) 2X Intel 6 Core Xeon X5650's with Hyperthreading 32Gb's of Ram (Will be upgrading eventually to 128) 2.5Tb's of hard drive space (with 3 bays still empty) 2X Radeon HD 5700's (looking for suggestions for what to upgrade too as this is my bottleneck right now) So... I can't vote as Apple isn't even an option
My main computer is an iMac running windows, which is around 3 years old. I also have another 8 year old pc and a 11 year old pc.

My computer is about maybe 10 years old.... I got it back in '08 as a gift from my parents, it being a brand new Dell HP Pavillion with a HP W2207h monitor and Altec Landing speakers.... Now, it really doesn't work to hot, just last week I got a message on my screen urging me to call dell about a recall on my graphics card that ended in 2012....
To be fair, it'd be hard to get them all, or even get close. Even all the motherboard manufacturers would be hard to get, but it seems he tried to go for all PC manufacturers. There are way to many people making prebuilts for them all to be included
Mine was originally put together way back in 2011. I've since replaced the old GTS450 with a slightly less crappy GTX650Ti and added an SSD. Otherwise it's just a Intel i5 2500K on an Intel (remember when they built MoBos?) motherboard with just 8gb of RAM and a 1TB WD HDD and a 250ish GB Samsung 850 EVO SSD. I'm surprised it still runs as well as it does.
I have a 2002 ibook a 2006 acer aspire an old hp Compaq from early xp era a 2007 macbook a lenovo ideapad from 2013 a lenovo g50 from 2016 and a custom ryzen tower I built in July of 2017
