Laura's Linux Computer

I last built a computer for Laura in 2016, running Xubuntu. Parts order:

  • Cooler Master NSE-2000-KKN1 micro-ATX mini-tower case: $46.99
  • Corsair CX600 600W ATX12V v2.3 power supply: $54.99
  • AMD FX-8350 Black Edition Vishera 8-Core 4.0GHz AM3+ processor (Passmark: 6086/1582): $149.99
  • ASUS M5A78L-M/USB3 AM3+ AMD 760G uATX [4x240 DDR3 2000/1866/1800/1600/1333/1066 SDRAM 6 SATA 3Gb/S ATI Radeo HD 3000 GPU 2 USB 3.0 4 USB 2.0] motherboard: $54.99 + $1.99
  • Crucial Ballistix Sport 32GB (4x8GB) 240-Pin DDR3 SDRAM 1600: $129.99; or G.SKILL Ares Series 32GB (4x8GB) 240-Pin SDRAM DDR3 1866 F3-1866C10Q-32GAB: $129.99
  • Seagate Desktop HDD ST1000DM003 1TB 64MB Cache SATA 6.0Gb/s 3.5-inch internal hard drive: $49.99
  • Samsung 24X Internal DVD Writer SATA Model-SH-224GB/BSBE OEM: $19.99

I generally went pretty cheap on this unit, trying to squeeze it into a $500 budget. The prices listed above come up to $509. I later added a PCI board to add a USB 3.0 front panel interface (which the box supported). I'm not seeing a video card, so CPU must have had online video. The hard drive died later, and was replaced with a SSD. Keyboard/mouse/monitor not specified, so we used whatever we had on hand (probably from old system). Same for speakers. Keyboard and mouse, and probably monitor, have been upgraded since.

There is no need to go that cheap again, but it has been a pretty adequate computer, and her requirements are fairly modest.

I won't bother linking to everything I considered here. After some discussion of Mini PC options -- roughly a 5x5x2 inch package with built-in video and wi-fi, designed to sit on desk or even on a rack attachable to the back of a monitor -- she decided to let me build another mini-tower box. I sketched out something in the $800 range, and she approved. The following is what I wound up ordering:

  • x CPU: AMD Ryzen 5 9600X (Zen 5) 6-Core 3.9GHz Socket AM5 65W Radeon Graphic Processor: $179.99 [*free SSD w/purchase, 512GB] -- supports DDR5-5600, no cooler; released 8/24; $178.99 at Amazon.
  • x Motherboard: ASRock B650M Pro RS WiFi AM5 AMD B650 Micro ATX: $139.99
  • x RAM: Crucial Pro 64GB (2x32GB) DDR5 5600 (PC5 44800): $139.99
  • x Case: SAMA 2851 ATX Mid-Tower PC Gaming Case, 4 ARGB PWM Fans, Black: $84.99
  • x Power Supply: Corsair RMx Shift Series RM750x 80 PLUS Gold Fully Modular ATX: $89.99
  • SSD: Samsung 990 EVO PLUS SSD 1TB PCIe Gen 4x4: $74.99

* CPU includes free: Team Group T-Force Vulcan Z 2.5" 512GB SATA III NAND Internal SSD: valued at $37.99

I originally listed a CPU Liquid Cooler: Corsair Nautilus 240 RS 2 RS 120 Fans: $85.11, but on checking out it came with an extra shipping charge ("from Canada") and delivery was kicked out almost two weeks, so I deleted it. I'll shop elsewhere.

Total (no CPU cooler) $747.06. Delivery Friday, June 27.

Further notes:

CPU: PassMark: multithread: 29997, single thread: 4570; CPUmark/$ 167.59. Clockspeed: 3.9GHz; Turbo Speed: 5.4GHz; Typical TDP: 65W. Cache per CPU Package: L1 Instruction: 6x32KB, L1 Data: 6x48KB; L2: 6x1024KB; L3: 32MB. CPU Mark relative to top 10 common desktop CPUs is 4th, below AMD Ryzen 9 5900X (39,015, $258), above AMD Ryzen 5 5600X (21,861, $129). List of "machines with this CPU (or similar) range from $1199-1699, all "gaming" machines with 32GB RAM, 1TB M.2 SSD, 650W power supply (where specified, most not), various graphics cards (3 have NVIDIA GeForce RTX 4060; also Radeon RX 7600, NVIDIA RTX 5060). Two most expensive have water coolers.

Motherboard: I wanted AM5, with 4 DDR SIM slots, and thought WiFi might be a plus, but otherwise I wasn't very demanding. I like the idea of BTF wiring, but I'm not finding much info on that count in the motherboard spec sheets. ASUS and ASRock are brands I've bought in the past.

Case: Laura wanted smaller, but not much variation in ATX cases, the main new trend is to move the wiring and possibly the power supply off to the side (instead of above or below). Micro-ATX cases are available, but are not cheaper, and not much smaller. Laura likes the gaming lighting, so I leaned toward cases with more glass.

Some size comparisons:

  • PCCooler CPS C3, 6 fans, BTF, power supply on side ($103.99): 415L x 295W x 368H.
  • SAMA 2851 ATX Mid-Tower, BTF, 4 ARGB fans ($84.99): 475L x 285W x 398H (18.7x11.2x15.7).
  • Zalman P30 Micro ATX, 3 fans ($84.99): 429H x 235W x 453D (16.9x9.25x17.8 inches).

SSD: CPU includes a bundled 512GB SSD, but it uses SATA instead of M.2 NVME connection. M.2 should be faster: according to PCIe generation: 3.0 (3500 MB/s), 4.0 (7500 MB/s). 5.0 (10-12000 MB/s), vs. 550 MB/s for SATA. Motherboard has: 1 Blazing M.2 for type 2260/2280 PCIe Gen5x4 (128 GB/s mode); 1 Hyper M.2 (64 GB/s), 1 M.2 (32 GB/s)

Power Supply: Notes: 80+ Bronze vs. Gold certification: former is at least 82% efficient at 20%, 50%, and 100% load; latter at lest 87% efficient, so less heat waste. In between is Silver, and higher is Platinum. 80+ is below Bronze, at 80% instead of 82%. ATX 3.1 has a new cable used for high-powered video cards (12V-2X6 vs. 12VHPWR). MSI MAG A550BN ATX80+ Bronze (550W): $54.99 -- ATX 80+ Bronze (650W): $74.99 -- ATX 80+ Bronze (750W): $94.99 -- ATX 3.0 80+ Gold (650W): $99.99 -- ATX 3.1 80+ Gold (750W): $109.99 - compact sizing, flat cables SAMA GT650BK 80 PLUS Gold ATX 3.1: $64.99 -- GT850: $124.99 Corsair CX CX750 80 PLUS Bronze ATX: $89.99 (not modular?)

Miscellaneous Notes

Motherboard form factors (DTX boards less common; there are some larger form factors, but no need to consider them here):

  • ATX: 12-inch length, width of 6.7-9.6 inches; usually 7 expansion slots, 4 RAM, CPU.
  • Micro-ATX: 9.8-inch length, width of 6.7-9.6 inches; max expansion slots 4.
  • DTX: 8-inch length, width of 6.7-9.6 inches.
  • Mini-DTX: DTX with width of 6.7 inches.
  • Mini-ITX: 6.7-inch length, width of 6.7 inches, can mount on ATX holes.
