fuuko: Move to new platform

The move already occurred on Tuesday, but I was too lazy to commit it.

 ## Hardware
 
-HP MicroServer Gen8 with an [Intel Xeon E3-1220L
-v2](https://ark.intel.com/content/www/us/en/ark/products/65735/intel-xeon-processor-e3-1220l-v2-3m-cache-2-30-ghz.html)
-and 8 GiB ECC RAM (1600 MHz). It isn’t the best choice, but I already had it
-lying around and it is acceptable after changing the CPU from the original
-Celeron. I decided not to use another consumer-grade computer for this, since
-the server offers ECC memory and therefore should be more reliable.
+Custom build frankensteined into a HP Compaq dx7500’s case (with all garbage removed).
 
-The SSD (Intel DC S4500 480GB) is connected to the first drive slot in a 3.5 ″
-adapter. I originally wanted to connect it to the internal ODD SATA port, but
-since it only supports SATA2 (3Gbit/s) and does not support booting from it,
-requiring an additional boot drive, I decided against this.
-
-For storage it has two Hard drives (Seagate Exos E 7E8 ST8000NM000A and WD
-Ultrastar DC HC320 0B36404) in BTRFS RAID1. They are connected to the 2rd and
-3th bay. Bay 3 is only SATA2, but that should not be the bottleneck.
+ * Motherboard: GIGABYTE B450M S2H
+ * CPU: AMD Ryzen 5 1400
+ * RAM: 2×8GB GOODRAM DDR4-2666 CL19
+ * PSU: be quiet! System Power B9 450W (the dx7500’s Lite-On didn’t have an 8-pin CPU connector)
+ * SSD: Intel DC S4500 480GB
+ * HDD: Seagate Exos E 7E8 ST8000NM000A and WD Ultrastar DC HC320 0B36404 (both 8 TB) in btrfs RAID1
+ * GPU (required for text console/firmware due to lack of integrated graphics in R5 1400): ATI Radeon HD 4650 (to be replaced with a fanless SUNIX VGA0411/Volari Z11)
+ * Case fan: Noctua NF-A9 PWM
