One of my colleagues has been attempting to get this going for some
years now. It has not been overall a success to date.
It's a lovely idea: personally I despise our throwaway culture,and have
spent thirty years or more repairing things for a living. I no longer do
so for (hardly) anything newer than late '80's audio as it is totally
A few of the problems we have encountered with recycling old Windows
boxes are as follows:
1. Poor build quality and design life of 5 years.
We almost exclusively sell HP desktops so that's what we get back in
large quantities. However, they come back because they are broken as
often as because there is a replacement cycle.
The broken ones usually have a dead disk, which can be swapped. But all
new disks now are GPT/2K sectors and are not supported by the old BIOS
which cannot be updated to one that works (well, of course, it CAN - but
at the cost of several hours faffin' about and who exactly is going to
pay for that several hours? Us?)(this partly because HP no longer supply
BIOS updates for machines that do not have a in-force warranty, and even
when they do it does not support GPT on old machines).
The ones that do not have HDD failure soon will - so the same issue arises.
If they don't have disk failure then the capacitors on the board are on
their way out OR the PSU is dying. Also the chipsets seem to develop
grown errors after many power-on hours.
2. Workstation-level PC's are a better proposition and we usually get a
couple more years out of those as they have better components in them.
The GPT/2K and BIOS update issues remain, and they are dog-slow.
3. What we do reuse is server-grade hardware. Small HP tower servers ca.
2010 make quite good Linux desktops, I'm using one at work myself at the
moment, and they support enough memory to be useful (ie 16 GB).
It's notably slower than a modern machine but good enough for web,
scripting, etc, and supports GPT.
Bigger rack servers work fine as low load infrastructure and parts are
readily available and cheap second-user (not such an issue for
Enterprise level drives/memory) - but I would not sell one to anyone for
use in production!).
3. We do have a few people with re-purposed HP desktops converted to
Linux. They are getting on OK but they need support which we have to
supply and we charge them for this (this is our business model anyway).
It is not now, and not likely to become, a profit centre. Also we have
to keep swapping out the machines as they fail after 6-12 months. It's
not really working.
4. The final point is that for Linux (for ANY OS) to work well it needs
decent hardware and adequate working memory: I would suggest 8GB as a
bare minimum, 16 is good, 32 better. 128GB probably is nearing excess.
Old machines usually only support 4GB max, and that is old RAM which is
more expensive than new RAM!
I have just built myself a new main workstation which triple boots. My
work OS is Kubuntu. It has a 5820K at stock with 32 GB of RAM @3200 and
256GB Samsung m2.nvde SSD 3GB/Sec and a 750Ti Nvidia card (to be
On this machine Kubuntu is a joy to use (and I am typing this on it). I
have to have two other disks each with Windows on them (one for games
not available under Steam on Linux, one for my music Workstation as the
plug-ins and Cubase/Wavelab only work under Windows, sadly).
For people to know just how good Linux really is, should we not give
them modern hardware?
Take a look at this link:
Just as an example: you can get a Zoostorm AMD A8/8GB for GBP 229.98
This will be a very satisfactory and fast Linux box.
And if you have to pay for set up and recycling time as I do, works out
at the same real cost as recycling and sorting out an old free Windows
box which will have nowhere near the performance, reliability,
upgradability or life expectancy.
As I said at the start, I despise throwing things away. I had my last
car until it was 20; my new one is 10. My main monitor loudspeakers were
purchased in 1989; my compressor-limiter in 1979. But these are stable
The hardware in the PC is still evolving rapidly and is nowhere near a
plateau, so old gear really is old.
I don't want to put you off. Just my opinion.
