And yes, this goes exactly where  you might think it will. 

The laptop I bought from PCS has had a long life. The battery for example, with no reason failed, giving  maybe half an hour so.  One of the speakers never worked from day one, but was rarely needed when headphones were used. So WTF, right? I forget the name of the laptop I bought which was one of the re-branded Clevo laptops (p151sm1), but it worked well. Back when 8GB of RAM was loads and a 4th Gen i7-4700MQ processor was really nice and 120GB was something to write about and booted faster than anything Windows had going. To be fair, still boots faster.. These days the laptop is relegated to HTPC. 

My Asus desktop is showing its age. An eight year old i7-3770S, even bolstered with 16GB DDR3 and SSD just doesn't cut it anymore. My search for the 'right' desktop began. Sort of. 

Before that really takes place, I'm going to harp on a lot about PCS's lack of Linux support since I've had one of their products (and I'm sure many a person has) for over 6 years with no software problems or compatibility issue using Linux. The problems were all hardware. It's almost like Windows needing to be compatible with Linux  for quality, unless nothing is needed more than Fortnite.

And now, my dear readers we come to why, in the year 2020, the lack of support for Linux on bespoke hardware is laughable when Dell and HP sell business class laptops and desktops, as does Lenovo if you are feeling like a enterprise level server. Other bespoke places in the UK are managing to create a product range, not limited to a single place. 
Other company's websites use the same method and description of options/configuration as PCS does. Assuming most bespoke companies ares buying the same core hardware I think is a safe bet. That is to say, if others companies can create OOTB Linux compatible on basically the same pre-fab hardware, PCS can call themselves specialists, but doesn't seem that special to me.


Linux drivers in early years and were annoying, Fair enough. That hasn't been the case for more than a decade.. Nowadays things just run OOTB these days. Even my detested fights with printer drivers are  painless. 
If printer drivers don't work, drivers are supplied by Brother HP, Epson, Canon, Xerox, Lenovo.. The usual printer names you may recall. 

If gaming is more your thing, support for playing has advanced light years. Steam's Proton and (even WINE directly) takes Linux into consumer areas and gives a flexibility of hardware that Windows users can only weep about. I'm not familiar with using GoG, but Steam Play is pretty good with getting stuff that previously could only work on Windows. To be fair, however, it's not perfect.

The final point is that if someone is plonking down hundreds or thousands of pounds, any product needs to be special. For example, Porsche Design. Some of their products are odd. Would I have bought a Porsche Design phone? Probably not, but only because the cost. That doesn't change the fact that it looks amazing and special. Bespoke PC's with shelf level hardware are not special unless they are made so. Design the products, and then they will be worth   
A few bespoke places appear to have got this message. I comment on how good they are but having only a few models just is easier. You can still have Windows even though these machines are not rated for that OS.
