If I do find that the bridges don't provide any improvement in SQ, I will sell them. I may even begin to move away from x86 computers and dive into ARM SBCs like the Khadas Edge 2, powerful enough to be a desktop computer. I have been really tempted to try an M1 Mac Mini but I just don't trust Apple's scummy business practices enough to drop several hundred pounds on proprietary hardware further restricted by locked-in software. If it breaks, only Apple can fix it... Might wait and try and get an M1 one at second-hand prices. The Mac Mini is a small single board ARM-based computer in an oversized enclosure but with better software support than ARM developer boards.

Just received a very very capable PC; a HP Z240 SFF (small form factor) computer for the tiny sum of £140 including shipping. What an absolute steal this is. It is a modular server-type PC with rich input and output options. Let's analyze what I got for the spend.

-Four low profile PCIe slots at the back. Gen3 speeds, two x1, one x4 and one x16.
-One PCIe Gen3 x4 M.2 NVMe drive at the front with integrated heatsink. Rejoice! 240GB M.2 drive pre-installed with Windows 11 Pro.
-Two USB 2.0 and two USB 3.0 on the front panel.
-Six USB 3.0 on the rear panel.
-Three Display Ports for multiple monitors. 4K resolution at 60Hz refresh rate is possible.
-Gigabit LAN ethernet, COM port, line-out and PS/2 ports
-16GB (2x8 dual channel) DDR4 2133MHz RAM
-Four SATA3 ports
-USB2.0 and 3.0 motherboard headers
-LGA1151 socket for 6th Gen Intel processors. This one has a quad-core, octa-thread Xeon CPU rated at 80W TDP. Going to swap it out with a passively cooled 2-core 4-thread i3-6100T rated at 35W TDP.
-Durable metal case for EMI shielding.
-Tray for HDD and SSD expansion.
-Optical drive with CD/DVD drive installed. Will upgrade to SATA Blu-Ray drive.
-Second bay for more storage. Front panel is removable so I could fit a PowerWire Bitzie in there with some modification.
-SD card reader on the front panel too.
-Have online manual and documentation for motherboard. Easily available device drivers.
-Small compact power supply. Hopefully no coil whine.

What a buy!

Impressive hardware, fully loaded. Hope it works and sounds very good.

In December, I got a Dell Optiplex 7010 SFF PC for £95 after I bought a set of feet for it and upgraded the RAM from 4GB to 8GB. Only two PCIe slots, no USB 3.0 and DDR3 (slower than DDR4) RAM. I will sell that one on soon.

This latest HP chassis has enormous upgrade potential and can house multiple storage drives as well as hold my S/PDIF and USB Pink Faun soundcards securely, still leaving two free slots for wi-fi/cellular networking and potentially a second NVMe M.2 SSD. So many options. I will post some photos when next on the desktop and after I have dismatled it for a thorough clean. The 150KB size limit here means I have to edit photos before being able to upload them. I should learn to host them elsewhere then link them on here instead.

Tomorrow, I have a Minisforum UM690 mini PC due, which should be a beast. This uses a Ryzen 6900HX processor and is the first time I will have used AMD instead of Intel. The integrated graphics are going to be game changing and the RAM is DDR5, which I could upgrade above 4800MHz to further push graphics processing performance. Integrated graphics have come a long way for gaming/emulation and are useful for other things too. Uses liquid metal instead of thermal paste as the contact interface. Can't wait to look through the BIOS and explore new possibilities.

Looking to keep the UP Squared V2, the UM690 and the Z240 SFF then sell all my other computers.
