Very good. Better not let "Mrs Franken" See that.... :-)

Back when Jim and I first started iDevCloud it ran in the back part of the FrankenLab in my basement. Being all Power5 back then it was 2 full racks of gear plus routers and switches in a wall mount rack. I was able to capture much heat for hot water in the summer and much of the cooling came from water used to irrigate in the summer. In the winter the heat just went into the house through a large duct that evacuated the heat to the family room.

Still rang up a $600 electric bill! :-)

Isn't there that show about Hoarders ? :-)

I have a lot fewer racks than you but the same issue, especially when it
comes to laptops. Let's see......Mac, Surface, Thinkpad, Dell, etc......

And if you want to learn the hardware you often need a lot to really get
into it enough to be even approach becoming an expert.

-Jim has so much stuff his stairway nearly collapsed bring down a UPS
big enough to power it all.
-Pete had 0595s holding up tables in his lobby and tape drives on
shelves in the bathroom before he moved.

See https://wiki.eth0.nl/index.php/LackRack for a useful way of stacking
equipment. I used to have my back-up uplink in my bathroom through a
hotspot similar to the XFinity sharing thingies, so I had a sealed outdoor
access point hanging above my bath tub on PoE. All my extension cords had
an equal length of cat5e with female sockets piggy-backed on them for use
during the summer.

-I have 5 IBM Racks full in my garage plus one live one in the basement.

You need a very tolerant spouse!

This is so true. It helps if you have a spouse with a similar hobby, but
then again, that only doubles the mess. I used to have twinaxial and a
bundle of single mode running around my flat, but after I moved I had to
switch to all copper due to practical concerns.

Something which's also underestimated is the cost of electricity -
especially in urban environments. Operating a model 250 24/7 will cost you
around EUR 20.00 a month in power usage. Newer models yield more
performance per Watt, but ideally you want a "remotely operable" power
switch so you can IPL the machine when you need it. More than 60% of my
energy bill is consumed by my "toys".

Ditto the responses of Larry and Henrik. Unless you plan on needing to
learn the hardware aspects of IBM i, your time and money is much better
spent getting an instance in the cloud.
