Pretty sure that is an Inwin Q500. I had one for a long time.
When I moved this last year I had to get rid of the case but I wish I had put it up for free on here just pay shipping come to think of it. It was a very unique design with the pull out mobo tray and the mid tower psu slot.no definately not, similar though... I had an InWin Q500 also, probably my second favorite case... had a saved search on ebay for years and no love
although did find my 3rd favorite on ebay which was the Rocketfish branded lian-li case... built a 2006 "dream rig" dual 8800GTX SLI, QX6700 OCd like crazy on water etc
my favorite case,which i've had for 6+ years now, is the Cooler master HAF 932. i don't have a nice pic of my actual case, mainly because its a mess right now but here is a reference pic.
my next case, i'm looking at the thermaltake wp100 or the thermaltake the tower 900 for a custom water cooling loop build.

Mid-tower Super Flower SF-201 all black from Directron.com $150(pricey)
Bought it early 2000s, fully removal-able MOBO tray, removal-able 5 bay HDD cage, 6x 80mm, front fan filter, lite all Al-Mg alloy body.
All case fans were mounted with reusable plastic rivets, and all fans had grills even on the inside.
Bought a 2nd one to rivet them together via the side panels and replaced the feet to casters to hold a gutted UPS and custom watercooling, later swapped out the custom WC with a early gen AIO that was designed to mount in 2 large bays (forget the name).
When I upgraded from Athlon XP single core based to the AMD 2x CPU I went back to a single case and bought a side window for it. It last held my 8GB, Q6600, EVGA 9800GT 512MB system.

First aluminium case in 2001 with metallic brown painted sides/top and car quality paint/lacquer.
It cost £270 which was ridiculous at that time.
Its sad the internal size is a bit small for todays PCs, gfx cards are a bit long and the cooling isnt up to the job.
It looks great and I still use it for my spare PC.
