Here's some that I've had before I post what I have now.....
My #1 Favorite Vintage Case I ever had was a Compaq Deskpro 8086/80286/80386 clone that belonged to a GEM Computer Products 386 I had. I'm still looking for more like this. Might re-comb the thrifts in Alabama next year to see if I can kick more up.
I also had the Deskpros as well - a 286, and a 386. The 286 was ruined by rain, the 386 I sold on E-bay before moving to Washington, I MISS that computer. I kept the 286 on a wobbly table for a short while - every time the Seagate ST-251 read or wrote to the drive the table would start "dancing" - 🤣!
Now for What I CURRENTLY have that's retro
The top computer is my Tandy 1000A of course, below it is a New-Old-Stock Case I bought from a California warehouse surplus company in 2005. It's branded "Songcheer" and it's an XT form factor case with a 150 Watt PSU. It's home to my current 486 retro-gaming rig and retro-game Dev machine.
Below is the GEM Computer Products 286 I have, which uses what I think might be a SongCheer AT clone case - it has some similar features to the Songcheer XT case above, though the GEM is steel, the Songcheer is aluminum. Yes, I like GEM Computer Products a lot, it seems they used cool cases up until the 90's - especially that first one.
