In July 2005 I decided to build a new PC for MSFS and pmMCP from carefully selected components.

In this Coolermaster Centurion 531 with an Enermax 490W powersupply, the mainboard is an ASUS-A8N-SLI Deluxe, AMD Athlon 64 Venice 3500 with Zalman CNPS7700-Cu and Corsair Twinx1024-3200 Mb DDR SDRAM 400Mhz matched pair memory. The videocard is a Gigabyte GV-NX66T128VP, Harddisk Maxtor DiamondMax Plus 10 250 GB, 7.200 rpm, 16 MB, SATA/150

As you can see the CPU-fan is pretty big and hangs over the memory bank slots A1 and A2.
And so it turned out that in the A1 slot the memory bank with performance-leds on top did not fit under the zalman processor cooler

The supplier allowed for a quick swap for equal-type memory but now without the leds on top.

A happy end after all.
