    I've got a number of home brew projects I want to do.
    1. Some small with maybe a small circuit or Arduino board inside...
    2. Some medium like the size of a modem or router or mobile transceiver...
    3. Some larger like maybe the size of a desk top HF rig...
    Can anyone suggest a good source for reasonably priced cases in small quantities?
    Ditto for 25 to 50 similar sized cases.
    Thanks for any suggestions.

    Easy:

    1. go to www.eBay.com
    2. Type into the search bar: "Electronic project box"
    3. Spend the next few hours perusing the bazillions and bazillions of choices - plastic, metal, large, small, singles, lots - you name it.
    4. Buy it! (them!)

    :)

    Seems like people enjoy parting-out Heathkits! I found a nice Heathkit cabinet on e-bay for a bargain price. I built an amplifier into it.

    Old Heathkit HD-15 phone patches can be had for $2 - $5 at most any ham fest and make GREAT project boxes! I have a fair number of these boxes that are reworked as "fake heathkits" to provide Heathkit looking functional devices that Heath never actually made.

    Other times, I just prowl a Ham Fest looking for most any old box for dirt cheap - old 12-volt RS power supply & slope front hacked up case with 20 ragged holes - it's amazing what 12-point cover stock "artwork" panels can cover up! In this case, it was for my Heathkit cabinet fan system.

    If you're at all clever, cool boxes can be practically free if you just apply a little creativity.

    Note the "before vs. after" of the boxes used for the fan system - just junk from the free table at a ham fest.

    Hammond Industries of Ontario, makes enclosures of all sorts. Available from zillions of electronics vendors. BTW, they also make transformers that can fix up your Boat Anchors or be used to power projects. Hammond goes back to early days of radio and has a small amateur/consumer radio museum.

    https://www.pomonaelectronics.com/products/boxes/boxes-and-covers
    Pomona Electronics of California also makes great enclosures, as well as test leads, adapters, etc. Again, available everywhere.

    Bud Industries makes all sorts of enclosures from small cast boxes to large frames and extruded Euro-boxes. Bud is a name known to old timers in radio!

    Dave. Your "Fake Heathkits" are works of art!

    Hammond and Bud have nice cabinets, at premium prices.
    It's more fun to adapt some used cabinet, at prices one can afford without too much pain.

    This might be useful to 'metal bashers'.... home made bender.

    Boxes and 'ally' chassis seems be like rocking horse manure these days, in my younger days I could walk into the local Radio shop and buy whatever sizes I wanted..... that's when we used 'proper' electricity and not flea power.

    You can fabricate cabinets using aluminum extruded angle stock and sheet metal available at home improvement centers. For example, the cabinet that I made for my 160-meter single band linear amplifier:

    Hand seamers are also very handy to bend sheet metal. For example:
