Let’sstart
withtheinitial
inspiration.What
madeyouwant
tobuilda PC
withanexternal
refrigerationsystem?
Matt:A mixtureofmy
refrigerationcareer
andanobsessionwith
buildingcomputers.

The interior
looks amazingly
clean. Did you
make that PSU
shroud and interior
cover yourself?
Matt: Yep, it’s all made
from 3mm gloss white
Perspex, and involved
lots of measuring and
making templates. PC
cases are always full
of mesh and holes,
but I want a clean,
flush look, so I had
to hide it all. Gloss
Perspex was perfect

an Eliwell controller and probe
to control the temperature, and
then resprayed the whole thing
in BBQ black and fitted an RGB
LED strip led to finish it off!
The refrigeration unit basically
cools a bath, and an internal pump
circulates the fluid from the bath
through the PC. It’s connected
using thick car hose and 14mm
push-fit fittings. A Y-splitter on
the inlet ensures that the CPU
and GPU both receive coolant at
the same temperature, and then
another Y-splitter is used to run a
single pipe back to the chiller. It’s
very quiet when it’s running – it’s
just like a normal fridge really.
There’s no radiator, reservoir or
pump in the case; it’s all handled
by the external chiller. This setup
also helps to keep down the
ambient temperature in the case.
For my next build, I’m going to
use a slightly bigger case and fit
the refrigeration equipment in
the bottom of it in a thermally
isolated compartment, making
a one-box refrigerated PC.
