I had the same thought, I have a P182
I have two of the same case, one green one black, both a hair bigger than a P182...but not as big as this thing. I actually have no idea what the cases are, just old with 80mm fans everywhere, ugly plastic front with a door.
Green one houses my AMD Barton XP2500+ on an Asus A7N8X-E Deluxe w/ 2GB RAM and 9800Pro. This replaced a P4 2.6GHz 1GB P4C800-E Deluxe system with 9700Pro I sold to my mom. Not right away...I built this from used parts later for a 98se/DOS gamer. I have 3 copies of legit legal 98se CD keys, but never found a working disk (dunno what I did with them, I have Win95 on a set of floppies lol) so its running 2000 and can't really game (terrible OS). My mom still uses that P4 system unmodified since I bought it new in early 2000's. That was the only system I ever could and did afford to buy new to this day. Before that was a Pentium 533 Viper 770 that lasted forever, and the earliest I recall was a Kaypro10...but parents helped with those.
Black one had an AMD FX60 system on I think an A8N32-SLI...got it stupidly low priced when Core 2 hit (I think it was $200-250 for the CPU/MOBO combo lightly used). Got a 7900GTX for $200 as well (I think they were still $400-500). I ended up parting it out later, selling the GPU/RAM/PSU, HS/F, and HDD (got a couple hundred around '09). Still have the CPU/MOBO in the case...should still work.
Was replaced with my current system, an original 2.4GHz 4MB E6600 C2D on a GA965P-DS3 that was gifted to me used after somebody upgraded (to Phenom2 X3 720). I added 4GB RAM a used 8800GTS 640MB a HDD/PSU and HS/F and had a custom wood case for it. GPU died not to long after so I ended up with a 320MB 8800GTS and still using it today. I've got 1.47v on the CPU at 3.3GHz. It used to run 3.4GHz with less voltage, developed problems though.
I've been seriously debating throwing everything I have at another new build with Haswell and next GPUs...need to sell my car first. So many games I can't/won't play because I like high resolution and detail. My poor CRT is feeling underutilized.
