It's not PC hardware, but I'm still using my fathers Goodmans Magnum K-2 speakers... they must be forty years if they're a day!
The Samsung monitors in my sig are probably the oldest things that get used daily. Circa roughly 2006. I like to keep things fresh!
I've a 12" PowerBook G4 from 2006, use it every single day, it's sat on my arm rest of the sofa so I can browse usually whilst I eat dinner, or when the gf requires my company when she watches some crap tv. Never let me down and battery life is still about two hours.
My oldest daily use would be my microsoft ergonomic keyboard in beautiful beige that I use on my main rig. I was given it with an old PC and preffered it to my crappy wireless one so it's hung around. Not sure on age but must be early 2000s.
I use an Aiwa amp from the 1970s and a pair of OR speakers to go with it. My grand uncle donated them to me. As for actual computer hardware, I have a system from circa 1996 with an AMD K6-2 at 400MHz, an Asus P/I-P55T2P4, and 128MB of EDO RAM. Also fitted with a 3Com 10Mbit/s ethernet card and an S3 Virge 4MB graphics card, both from 1994. The CPU was probably upgraded after the system was originally built. I use this system for occasional testing.
I can't compete with some of the entries here, but I use this daily and I think it's just about celebrating its super sweet sixteen now.
Just looked at the back of my daily work PC, and see it's well over 8 years old. Big old metal beige case with an MSI i865 ATX board with a whole 1Gb of DDR400 and a Socket 478 P4 @ 3.04, oh and an AGB 5700FX graphics card for good measure. This was a high(ish) spec machine for Photoshop when it was built, and it still good for Word/Excel/Accounts. Seems a bit sluggish at surfing these days... Just tried adding 512 Mb DDR 333 to see if extra ram trumps lowered speed/bandwith.
I have a pair of celestion ditton 15xr monitors that I don't use every day, use them in the studio a fair bit and I'm not in there every day! they are from mid 70's so nearly 40 odd years old. One of my clients has a 1u compaq server that is running server 2000 thats pretty old in server land, I would guess its from 99/00. And there is another thread that popped up the other day about someone else using a server 2000 box.
Logitech Z-5400 (like the 5500's) - Got them in 2006, and they are just about the only piece of hardware to have survived my many clearouts and upgrades - a testament to their quality.
My keyboard (well, it's my brother's Cherry G80-3000), which is approaching 15 years old now and it's still as good as new (probably because it was in storage for several years until recently when I restored it).
I recently retired a beautiful pair of Mission 737 speakers coupled with some beautiful early 1980s Technics separates. All still working perfectly after 30 years, with a sound quality to rival even modern hi-fi setups.
my oldest daily use hardwares are a Telefunken valve amp and a telefunken valve radio receiver from 1960, with its matching telefunken light paper cone alnico full range speakers (new cabinet being under design). I'm currently replacing the din5 connectors for XLR ones. The amp had a dead selenium rectifier, replaced it by a valve rectifier stage. This is used as my computer audio . ps: I found the beauty lying down in the street
Following replacement of my macbook and monitor recently nothing I'm using was purchased before early 2010, I'm not doing too well compared to the rest of you. I imagine my case, PSU, keyboard, mouse, headphones, HDD's and monitor at least will be last for a good few years.
