Original Pentium III era hardware. Sent to a friend.
Side panel which pops off with a push of a button on the front bezel.
This needs some work if we're gonna convert it to ATX
Flattened/removed these little metal tabs
These clips hooked onto the old motherboard which used a non-standard layout.
The rear will have to be modified.
Actually, let's just cut it.
Cut out most of the rear.
Didn't want to cut off the very top of the rear end. Still, the case needs more work...
That is where this cheap donor ATX case comes into play.
Slice it in half.
Other side of case
Will preserve the back end as well so we can reuse it in the Optiplex
Cut off wheels are our friends.
Was really easy to slice through this one. Cutting the Optiplex was much more work since the steel wasn't paper thin.
Retrobrighted the case and painted a 5.25" USB 3.0 front panel ... slightly off but it's hard to find exact matching spray paints.
Dell Optiplex GX110 case
Corsair 750W power supply (cheapest name-brand power supply I found at microcenter at the time)
MSI Z270-A Pro ATX motherboard
32GB DDR4 3200 RAM (2x16GB)
MSI Armor RADEON RX580 8GB PCIe video card
Teac beige DVDRW drive
5.25 USB 3.0 front panel
Samsung 970 EVO 512GB NVMe SSD
Seagate 2TB 7200RPM HD
Left it in the sun a bit too long, some slight streaking is noticeable but only if you really look up close.
My motherboard's I/O shield is unfortunately missing... but did keep the original Dell PCI brackets.
The guts! Tidied up the wires in the 5.25 drive bays.
Lower part of the machine... the front panel is proprietary and was a pain to wire up. I don't have the HD LED working but everything else works fine (power LED, power + reset buttons).
That floppy drive is not hooked up to anything.
Here it sits in all its glory!
