Hi All,

I have been recommending Lenovo's Think Station computer
to customers.   But I really do not like how proprietary
they are.  Repairing them is impossible after the warranty
period expires as Lenovo is the only source of parts
and Lenovo won't sell you parts.

Anyone have a recommendation for a business grade
computers that use generic parts and are very reliable?

Many thanks,

I recently specced a couple of systems for a small business. I have always used Dell Optiplex machines for my small business clients. They're cheap, reliable (the systems they've been using are well over 6 years old, zero failures), and because they're business class machines, Dell makes drivers and firmware updates available for a long time.

I learned that Dell renamed the Optiplex line to the "Dell Pro" line (absolutely horrible move, they threw away decades of brand recognition). https://www.dell.com/en-us/shop/desktop-computers/scr/desktops/appref=dell-pro-product-line

I specced these out because they'll easily last for 6+ years and the PSU is Platinum, so more efficient (albeit only a few percent):

Now, these systems are DEFINITELY proprietary, in that the power supply and motherboards are specific to these systems, but... I treat business class machines as black boxes. I am not going to swap CPUs or motherboards. Literally the only thing I *might* do is install more memory and a bigger NVMe drive in the future. But that's highly unlikely, to be honest. These are damned near disposable computers, intended only for productivity work, not high end graphics processing or gaming systems.

When they are outdated in 4-6 years, my customer will just buy new ones, and they'll sell these on Craigslist or Facebook Marketplace after I've securely wiped them.

If you want a custom built system with off-the-shelf parts, I've used https://www.ibuypower.com/ for a couple of clients, and they make good stuff. But it's definitely for gaming computers, not plain old productivity machines.
