My first Atari was an STe in 1990 when I was 7-8 years old. I had it until the age of 15 when I sold it for money to save for a PC. It's been a long time but recently I got a lucky buy on an STe auction and I've finally been re-united.
Now... being the guy who usually does all the upgrades for other people... time for some FUN
The motherboard, a 5.1 revision with separate blitter. I literally bought the best capacitors money can buy, a mix of organic-polymer, film and ultra-high-spec low esr elcos. Also using Exxos 4700uf PCB capacitor kit which I usually reserve for Falcons
Here on the left you can see a beautiful Exxos PSU and 4MB of Exxos RAM. Plus a close-up of some of those special capacitors I mentioned.
Here on the right you'll notice the 32mhz prototype plug-in CPU and fast-tos switcher, plus a flash floppy drive (Notice the TOS switcher cable running inside the flash floppy drive
Here at the rear you get to see where I mounted a Pi-RGB which converts the STe output to pixel perfect HDMI, I installed the port above the external floppy socket
Here on the floppy side you'll notice an 8/32mhz switch
Here in the flash-floppy you'll notice an extra round-black push button switch, this is what is connected to the TOS switcher
What's this green device at the back? It's an ACSI2SD, which provides a very fast hard disk drive. It's better than most ASCI SD solutions because it is based on SCSI2SD, so it actually emulates up to 4x disk drives! So I can load up a partitioner, completely re-partition one drive and not have the other three affected, all on the same SD card. It is powered directly through that barrel jack to the internal PSU. The HDMI output port is just to the right of it.
Turned on and working as intended

To finish the icing on the cake, a suitable 4mb badge (A reasonably priced one from a seller on ebay in Poland, not the ST-Freakz £30 version... I'm not *that* crazy
