Update... Found out about the case... InWin A500. Here's a link to stock case pictures note the huge panel (no longer there) on the opposite side from the mobo tray.

in russian but the only good pictures I found (we won't go into my video attempt here...)
This mod is going downhill fast... for now I did slap the H2O in the current mid-tower.
I decided on a gloss red/gloss white (flat black accenting) but I'm finding the tower does not want to cooperate with my initial vision (which gets revised virtually every time I start work on the case). The front panel still needs to be filled, shaped and cut (design for the panel cut is complete) at least. I had envisioned completing it by yesterday and I'm still finalizing - it is getting closer though.
Other than the fun of the challenge or if you have a specific design goal in mind unavailable through commercial channels, modding old cases is not worth it (spent more than an average mid-tower just on supplies for this mod plus, it's frustrating as hell) although I'm gonna keep doing it, lol.
Any computer historians might be interested in the build list from this (Found on a label on the bottom of the case... June 2000) - I found it interesting;
InWin A500 w/Powerman 300W (no SATA but still works)
Pentium III 550E @550MHz - Slot 1
Aopen Pentium III AX63Pro
128MB SDRam PC100
ATI Expert 98 8MB AGP
Conner 4.3GB OT204 (not familiar with this thing - might be an accelerator card)
IWILL UW SCSI 2936UW PCI SCSI adapter
IBM 9GB SCSI HDD
Teac 8x CDR - SCSI
Mitsumi 3.5 Floppy Drive
Delta 48x CD-ROM
PCI V.90 Rockwell modem
Realtek 8139 10/100 TX
Windows 98 2nd Edition
Actually, I think it's a great build for it's time
