Time Computers (British) used to use that case, though with various different front panels, sometimes labelled "Time" and other times as "Colossus". It has one of those weird PSU mounts that is rotated 90 degrees and overlaps the motherboard, doesn't it? I liked those, I modified one to have 80mm fans in the top and mounted a dual Slot 1 mobo years ago.

indeed the psu is at a 90 degree angle and covers the cpu slot. My psu has a big fan above the cpu. Don't know if it blows or sucks air.

I seem to remember hearing that the original ATX spec stated that the PSU fan was meant to be mounted there and would cool the CPU... Though I do not remember if it stated which direction the airflow was meant to be in, if it did I am sure the PSU makers didn't listen anyway because I have seen ones which run different ways depending on who built it.

Strange when you think about it, most PSUs made in proceeding years had the fan at the back like the older AT type, but in recent years they have started placing a ~120mm fan at the bottom again.

AFAIK, the original ATX spec called for a fan blowing air onto the CPU to help it cool. Eventually people realized that blowing hotter air on top of the CPU wasn't that great of an idea (especially as CPUs started needing better cooling and systems started drawing more power), so it got switched back to the old AT-like style of having the PSU as an exaust. I believe having the exaust at the bottom was mostly introduced back to cater for cases where the PSU is mounted at the bottom, so they draw cooler air from the outside and take no part in the case cooling solution.

EDIT: Also, I believe having an exaust at the bottom of a PSU would actually hurt CPU cooling in an old ATX case where the PSU is mounted facing the CPU. In the original specs the PSU would blow air onto the CPU cooler, therefore helping it. An exaust fan would create a low pressure zone, reducing the amount of air the CPU cooler would be able to blow. On newer-style ATX cases with the PSU on top this would likely not be a factor, as the exaust would also help remove hot air coming from the sides of the heatsink.

Ugh, my old P4 tower came with a case like that - except the PSU was solid bottomed, and thus cut off a large amount of the airflow to the CPU fan. Thankfully, 2 GHz Northwoods don't run all that warm, although it definitely made the CPU fan head into the 5k RPM range under load...

The as-absolutely-inexpensive-as-I-could-get custom build I did in 2002 also used a cheap (Likely NOS) ATX case with the power supply oriented so it "hangs down" in the manner described. It was very annoying because it blocked the air intake to the CPU. This wasn't a major issue when it was loaded with a Duron 1GHz, but once I tried upgrading it to an Athlon XP 2400+, then it began causing serious overheating problems. I must confess though, I failed to recognize this as the cause until after I had already gone overkill with a massive solid copper heatsink with stupid-fast Delta fan and four additional case fans (I was kinda dumb back then). Of course, a larger heatsink only meant the fan was even closer to the PSU housing, which basically meant the fan was trying to pull against a near vacuum. :p

For a time I ran an Athlon 64 X2 in a case like that too... It used to hit 65C and upwards regularly, I didn't really care though because the system sucked anyway. Perhaps this case was a factor in the system not working anymore. I still think they were good for Slot 1 boards though, given the fan was also turned 90 degrees.

I picked up this PCV-W20 which was recently reloaded with a fresh copy of XP, but it crashes for obvious reasons. No worries because I have a bag of Polymers to fix it with. I think I'll opt for a small SSD as well.

Here is a view inside with the psu blowing air onto the cpu. I could reverse the airflow by flipping the fan in the psu, but i will testrun this system first to see how hot it gets.

I'm going to add a dual voodoo2 12mb sli setup to it, maybe swapping the vga with a 16mb vanta card, already installed 512mb ram. Going to put in a 20gb hdd. But i have to get a ultra66 controller first.

Got this for 20 pounds.

Will be more than enough for my GM gaming, i will certainly pass off on a Roland SC7. I would prefer the MU10 but those have been selling for double the price. It supports XG and i have quite a few XG midis songs that will rock on this. I'm flipping the finger to Roland this time. 🤣

Ahaha you Roland junkie. If it makes you happy you can donate me a CM-32L. I will gladly take it and not flip the finger to it. 🤣

Nuuu! I can't give one away, it's 2 different firmware versions, so completely different CM-32Ls. 😜
But i'm searching for a MU15 for a while now and they're about 80 euro here hence the FFFFUUUU! 😁

Naaahh you can EEPROM your CM-32L and it's better to use 1.02 anyways... If you want we can trade the MU15 for a CM-32L. 😎 🤣

^ Cool but why to use those old EPROM's? Much more of a pain to erase in my opinion.

Because cheap and available.^^

Nice find! Do you plan to use the sequencer function too? Wonder if it's any good. I tried the MT-100 sequencer once, but that doesn't have anything more to offer than a tape recorder.

I'll probably play guitar over it. I love to solo over backing music.
