Other side with original XP sticker

Original IBM model + serial # sticker

The rear, jerryrigged the rear fan and power supply in there... spare PCI brackets, zipties, some old motherboard standoffs and VGA fasteners did the job.

Front

The original guts, all filthy and disgusting. 2.0 GHz Pentium 4 with 1GB RAM

Overview of all the guts

I used some male to female Arduino pins to reroute the original NetVista power switch and LEDs to the motherboard.

Another shot... the SSD is chilling in a spare bay underneath the optical drive.

All fired up and running! Temperatures are fine, idles in the low-mid 30s and under Prime95 stress test, high 60s/low 70s. These cases are built very well and are TANKS! Also pretty easy to work with.
