Here's my latest build project (for my Dad). It's decently quiet because of the fans used (JMC, Vantec stealth) which are NOT all that quiet. The LX-6A19 was lined on the interior with Melamine foam with the interior (visible) side fiberglass sheet removed (bare foam). This made the foam much nicer to work with (no rashes!)
Compucase LX-6A19 (fan grills removed, cables stealthed)
Fortron FSP300-60PN (120mm fan, grill removed)
EPOX 8RDA+ (Zalman Northbridge cooler)
2x512MB GEIL DDR400 RAM (1Gig)
2500+ Barton T-Bred (195MHz FSB, 390MHz RAM)
Alpha PAL8045/Panaflo 80mm L1A (12V)
ATI Radeon 9200 128MB (fanless)
Pioneer DVR-105 DVD-R
Maxtor 80GB ATA133 7200 RPM 8-MB cache (silent mode)
Zip250 (not shown)
Fans: JMC 1225 (NOT L)

Total cost: $1050.
It's quiet but not silent. It'll be fine for my Dad's lab/office. Pictures below.
