Default The end of the road for the DIY PC?

Hence why the DIY'ers that will do this task are those that have
soldering stations. You know, the ones where you can dial in the
temperature. However, as pointing out in the videos to which I link,
others have been inventive in finding cheaper means of doing the
soldering, reflow, or desoldering.


"Soldering stations" are *NOT* intended for BGA work. boggle You
need at least hot air and preferably a controlled oven for this.

"Knowing how to solder" has nothing to do with it. This is not a
normal soldering operation.


It is if you have the right tools (or not how to fab your own gerry
rig). Again, the videos show NON-professionals doing the work and they
are not using $300 soldering or desoldering stations, either.


Unbelievable.

Not having sockets doesn't mean you can't DIY. It means the DIY'er will
need better skills than pushing stuff into a socket or slot.


It means that no retailer is going to sell this stuff to you.


It means they will void the warranty.


No, it means that they will not be in this market at all. The number
of DIYers who can do this is close enough to zero that it's not a
business.

As I mentioned, the most likely
scenario is that you order the CPU you want with the mobo you want and
the combo gets delivered to you with that setup.


No, the most likely scenario is that this business won't exist. If
there is any DIY market, you'll buy the board with the CPU (and
perhaps the memory, too).

A jobber at some point
after the chip manufacturer but before the retail/online vendor does the
work or is contracted out or however the vendor wants to get made the
hardware config that you order. Sometime later you want to replace the
CPU because it went bad, like you overclocked or overvolted it, or you
want a better CPU. Do you really buy a mobo with a CPU and then
immediately discard the CPU to buy a more powerful CPU and put that one
in? No, you buy your hardware list, fab the parts together, and
sometime later decide to upgrade. Users of mobos that have expired
their warranty won't care about what the retailer will sell them since
they already have it, it's out of warranty, and they've decided they
will change the CPU.


No, you buy a new board, too. The choices of CPUs will be very
limited, too.

I don't see that this will impact the initial or first sale of hardware
when you fab your homebrew host. You're going to build your shopping
list, get the parts, and slap it together. Sometime later you decide to
make changes. In this case, it's not a question of whether a retailer
will sell you a CPU and mobo separately and warrantly their users
soldering expertise. It'll be whether or not non-commercial or
non-volume users can purchase the BGA CPUs to acquire them to sometime
later swap out those CPUs. If you can't buy one BGA CPU at a time, it's
not likely you're going to buy 100 or 1000 of them to change the CPU on
your one home computer. My bet is some volume buyer will resell the
individual units at a markup and make some good money at it. Of course,
they aren't going to include a warranty with it.


You're dreaming.
