Just build it. The uBitX took me about 3 hours.
It is a cracking little beast.
What really will take the time is all the mods I have lined up

Just putting one together is very simple. Finding a box , cutting holes
and such takes a while. I made several mods to mine. Such as changing
the final transistors to another kind, several components were changed.
One major change for me was to change out the 4 or 5 capacitors in the
filter to widen the filter from about 1.7 to 2.3 KHz so the ssb sounds
better. Then the software changes. Some from others and a minor one or
two of mine.
Mr.Farhan did a very good service to the ham comunity with that unit.
Not very expensive, and works ok as is. Then others jumped in and have
some really nice software and mods to make it really work well for not
too much unless you use the fancy display that costs about what the
origional unit does. Even new cases cost almost half the unit. I just
hapened to have a minibox that only had a few extra holes in it that th
e uBITX just fits in.

Perhaps they will not be the most pretty ones ,but enclosures for the ubitx
and bitx40 or any piece of equipment can be easily made, at the size one
prefers , from low cost PCB sheets often available at flea markets. I
happily have a healthy stock.

In 1972, QST ran an article on a 80 meter SSB transceiver, solid state,
and the case was mostly copper circuit board. But he used some wood to
make a frame, which perhaps is more solid for a larger box than just
relying on solder to hold it together.
But as someone else said, there are lots of boxes out there, even computer
power supply boxes, that can be reused with a bit of patching. Slap a
piece of circuit board over one side to provide a "front panel", covering
up what was before it. Circuit board is certainly easy to drill and cut
holes in, easier than aluminum and way easier than steel. Though, the
move for consumer electronics is away from metal, so the days of satellite
boxes and other things that are metal are often in the post. I know years
ago someone here was thinking (or maybe had) built a power amplifier in a
metal "IBM compatible" computer case, which has potential, though I
haven't seen a really sturdy computer case in some time.
